I want to build a go kart like the one they have in https://

>>13940435
Good decision , OP. They say go karts have Mini Cooper handling without the failure Chrysler transmission and way to high price tag.

>>13940446
I don't know what that means. I just want to have fun in my yard and the street.

>>13940452
Well if that's what you want then don't buy a Mini Cooper. They are total shit for faggots who saw the Italian job reboot.

nice try

>>13940476
Surprisingly not bait. I just know nothing about any of this. I'm asking what the clutch does because it doesn't have any gears to shift or anything, right?
Does it allow for you to be stopped but the engine to still be running?

I'm really fucking new to all of this, which is why I started a thread for it.

What the fuck are you doing in an auto thread if your not asking about cars you forgot. Maybe it is you who should fuck off to go fail elsewhere.

>>13940500
>yes
Well that's one question answered.

Now, I know that it's not really a lawnmower engine, but it's something similar to that. Even then, I haven't seen anything about being able to control the speed on small engines like that. Or am I just blind?

>>13940524

why the hell would an engine not have any way to adjust the RPM? you're a fucking idiot and you're getting "le troled xd" by everyone here. ask on reddit if you want a thread without shitposting (only problem is all of reddit is a shitpost)

>>13940530
Ok stupid. I will help you out cause I'm a nice guy. The transmission is in the back on the motor. You take your hand and reach back behind you and flip a switch to change gears. The switch is located I between the chain drive . You have to reach back and stick your finger I between the chain while your driving the go kart to up shift. It's so fuckonf simple even a retarded asshole such as yourself can figure it out. Good luck OPfag.

>>13940435
How's the go kart project going?
Looks like your off to a good start, OP.

>>13940476
I don't think you know what a centrifugal clutch is; that wouldn't allow you to have any sort of throttle control, and if you just left it on an engine that was spinning while not moving the kart, it would destroy itself rather quickly.

>person has genuine questions about how low-cost karts run
>>OH NO ITS NOT A SHITPOST THREAD NOW I GOTTA MAKE IT ONE

Can't tell if bait post but if not...

OP, google search "manual throttle cable" and "centrifugal clutch"

Then check out these channels on youtube

Do some googling and don't talk to the catfuckers on with website.

>>13940435
Op, if you're really planning on doing this, I recommend getting the 6.5hp harbor freight engine; it's only $100 dollars and it's completely worth it. There's even a mount on the engine that's ready for a throttle cable, so you don't have to switch it out. I've abused the ever living crap out of mine and it still runs fine. You can find centrifugal clutches for as cheap as $25 as well, so your powerhouse will be pretty inexpensive. If you can, try to find a used go kart on craigslist or ebay near you; it's cheaper to buy one that's already made than to make one yourself in 99% of cases. I know this especially since I made my own, then my friend, a week after I finished mine, got an entire kart with a bad motor for free.

>>13940435
Op, if you have a horizontal lawn mower engine with no throttle, you could easily change the carburetor. Lawn mowers do have a throttle, but they're not usually used to their limits.
Also, consider putting in ~$120 more dollars into your project once you get it going for a torque converter; I just installed mine today and the acceleration difference is immense. There is a noticeable drop in top-end speed, though.

>>13941195
Would you say it handles torque better than a centrifugal clutch?
Not op btw

Make sure to use lots of glue and tape when you are putting your go kart together, OP. Good luck I know you can do it cause your a Mexi-CAN .

>>13941210
Yes, definitely. A torque converter is a CVT; it allows the engine to provide tremendous amounts of torque initially, then raises the ratio from engine to axle as you increase throttle.
Think of a centrifugal clutch like trying to start riding a bike in high gear; it's hard to get going, but when you're going, it's easy and manageable. A torque converter is like starting in low gear, then continuously shifting into higher and higher gears to get up to speed. In this case, you'll get to top speed a whole lot faster.

>>13941233
Oh yeah I know how they work. What sort of setup do you have? Just wanted to hear someone with actual experience

>>13941269

On my shitty deathkart we had a Predator 212cc engine which is the same as something you get on like a pressure washer. We just had a centrifugal clutch so it slips slightly when taking off then grabs when the engine gets to a certain RPM

My setup is as follows:
-One wheel drive on a live axle; one wheel can rotate freely on the axle.
-Hydraulic disk brake.
-Torque converter sprocket has 12 teeth.
-Jackshaft with 18 tooth input, 13 tooth output.
-Axle sprocket has 72 teeth.
-Wheels are 18" outside diameter.
-Independent front suspension, shared swing-arm rear suspension.

I made this thing to be good at going fast on streets and being able to clear a curb from the lower side, which it does nicely thus far. It's also really fun for light off-roading.

In the pic you can see my old centrifugal clutch and the brand new torque converter. It makes quite the difference!

Also, sorry if the photo is a bit blurred when you look closer; I was freezing my butt off and shivering.

>>13941340
When I said 'shared' swing arm, I meant that it was a whole piece. That is unless you were wondering how it is an entire axle with one freely-spun wheel. In that case, the answer is grease and some careful machining. I do, however, have an Idea of how to make a 4-wheel independent suspension setup. It's kinda weird, so I'll elaborate since someone brought up the idea again. See pic.
I'll try it someday in the future and tell everybody how that works out. I guess you could keep the shared jackshaft and use a single torque converter instead of the clutches and have a "locked differential" with independent suspension as well, so there's that.

As for the rear suspension I have right now, it's a pretty common setup, but mine looks very barebones and simple because I didn't bother making a rear piece over it. It's just a big hinge and some shocks to keep it where you want it.

The front suspension is a whole different story, though. It's some weird custom setup my buddy designed; I decided to use it rather than double a-arm because I already had the piece. I guess it would be described accurately as independent front swing-arms --I thought it would be terrible, honestly.-- , and it works very well.

>>13941364
I do have a youtube channel, though I don't have a camera that I can use other than my phone, so I get discouraged and annoyed and don't try to make videos. The only go-kart related video I have on it is me and my brother messing around with the engine while it's bolted to a board, ironically called "World's cheapest go-kart".

What shock/spring did you use?

How did you do the 2-piece axle though? Any pics? Mine was a solid axle and slid excellently but low speed turns were iffy. Wish I still had it to perfect but left it with a friend so he could do some work on it and never got it back before I moved. mine had no suspension but the frame did flex and you could feel it when driving it so there's that kek

>>13941332

>>13941398
It doesn't have a 2 piece axle, rather, a modified axle with a bearing for the other wheel. It was a simple job for a lathe. I took 4 pics while I was out there, but there's no way I'm going to spend more than 5 minutes in the ice-cold garage to take off the wheel to show you right now.

>>13941405
The frame is almost entirely made out of shopping carts. I was actually in the middle of making a graphic for /diy/ on how to make the frame out of shopping carts, but I only got through 1/4th of it before it was turkey day.
The hardest part of making the frame was being creative. That, and the tube coping. Bleh. Here's an old pic of it when it still had the clutch. I'm still deciding whether to put a roll cage or not, but I just love the sleek look it has right now.

>>13941369

>>13941446
Oh I see so one wheel has a bearing between it and the axle. I was confusing myself.

I would like more pics of some stuff but don't want to bother you to take any. I really want to make deathkart #2 and learn from my last build.

>>13941446

>>13941460
>because i dont have a welder
craigslist. $40. Become has welder.

Seriously though, people sell fluxcore/MIG combos from harbor freight as "broken" just because they have the polarity wrong from the factory sometimes. You flip the polarity and you're good to go.

>>13941475
Heck yeah, man, go for it.
I'm going to try to find some crazy way to combine a torque converter and a centrifugal clutch to get the benefits of both at the same time.

>>13941522
You could always have the clutch on the engine then run the chain directly to an idler with the torque converter on it.

>>13941548
I thought of that for a little bit too, but you might as well just run the torque converter since the input is now 2 centrifugal clutches away from operating. I think the best way may be to somehow have the input shaft for the torque converter and the centrifugal clutch be on the same shaft, so as the torque converter reaches it's upper limit, the clutch can grab on and push it a bit further. Then again, I've heard the top speed loss from a torque converter is from the friction of the band, so it's entirely possible that there's no way to achieve the top speed of a centrifugal clutch without disconnecting the torque converter manually while driving, which makes for quite the involved setup. maybe dog clutches to shift between the torque converter and clutch? I'll figure it out someday. Maybe.

2MB, 2560x1440px

>>13941588
I think if a band is involved in any way you will have slippage. I thought you wanted the clutch on there for a different reason than what you are describing. I think at the point you are talking it is probably worth it to just drop in a small motorcycle engine with a few gears.

How does the torque converter work when taking off from a stop? Just belt slippage to ease forward movement until at a certain speed?

>>13941602
There's no noticeable belt slippage at all, incredibly; although I'm sure it does every now and then. It's a very tight and beefy belt. The varied size of each end on the torque converter keeps it tight as well. When you take off from a stop with a torque converter, it pulls you forward incredibly fast as it's giving 3-4x more torque to the wheels than a clutch would at launch. Believe me, it's fascinating the difference a torque converter makes opposed to a centrifugal clutch during launch.

>>13941512
god i wish. alaska has fuckin shit for craiglist, unless its the usual broken down rusty ass bullshit that he know what he got

>>13941602
Dang, do you have an adjustable seat on that? And is that a makita angle grinder I see?

>>13941675
It did have an adjustable seat on it. It was waaay too heavy and couldn't move back much because of where the engine sat, but it was free from a vehicle I was parting at the time.

>>13941624
So I guess my question is without a clutch how does it not roll forward when you start the engine and when it is idling? The whole point of the centrifugal clutch is it doesn't try to move the kart forward until a little off idle when it grabs.

>>13941713
I wouldn't have been able to answer this question just 8 hours ago, but now I know: The torque converter also has a centrifugal clutch. It's a little different, but a centrifugal clutch all the same. It will usually pull you when you idle it initially, but after you break-in band a bit, there's an idle. This is speaking from just 2 hours of experiencing torque converters, so I'm not really an expert on this, but so far I'm impressed by the dang thing.

-live axle with both wheels locked for moar skids
-brakes? I suppose the standard Manco drums on there are "brakes" if you squint really hard
-engine is a 90's Suzuki 160 quadrunner with stock sprockets, makes anywhere from 12-15hp with, I shit you not, 11,000 rpm capability, top speed is around 50mph
-front wheels are tractor supply specials, 8 years old now
-back wheels are stollen from a craftsman lawnmower, 12? Years old
-lol what suspension?
-Seat is out of an old cuda (apparently)
-tries to kill me at least once a year
-I can't kill it

Me and a couple mechanic friends(have access to shops) are building one. Gonna be using a bunch of full-size car parts like wheels and such. Currently we got a 4pot Ford engine out of a Mazda 5 making 150ish HP, a VW K03 turbo, and we probably are gonna get a old firebird or miata for random parts to use.

I think it's gonna be a fun time welding this shit together.

When you're using car engines and wheels, you're a little beyond go-karts, man.

>>13948796
This, really. Cool stuff, but it's a *little* beyond a go-kart.

>>13949687
They use little engines from whatever they can get.

They control speed with the throttle.

Most go karts use either a centrifugal clutch which has two parts one on the engine drive shaft and the other is connected to it by spring loaded plates which only engage with higher rpm. The second part has a sprocket on it that is connected to the main axle.

Some higher end go karts use torque converters and I have no idea how those work

>>13950225
Whoops, didn't mean to reply to him.

One of the guys on our school's FSAE team built a kart powered by a GSX-R600 engine taken out of one of the old formula car builds.
