An old Jacobsen snow blower

Also it starts when I spray start pilot but stops immediately when I stop.

You using new fuel, and not shit thats been sitting in a can?

Also check the carb needle float, and pump if it has one. If it runs on starter fluid, then its probably a fuel issue. Dump a little fuel stright into the intake. Give it a rip.

It's new fuel. I've sprayed it straight from the plug hole and it doesn't even try to start.
Seems weird if this is a carburator issue, since it runs on start pilot and the plug gets wet.
It should atleast be trying to start.

If it is 2smoke check this guide http://www.mopedarmy.com/wiki/Fred's_Guide

it's a 4-stroke. I'm only guessing but it must have at least 10hp.
Did some serious snow with it last winter.
It worked when I put it to the garage, it worked when I took it from the garage, now that there's work to do, it doesn't start

did you let it sit with gas in it, or did you drain the tank and carb?

it might be gummed up with varnish, take the carb apart and remove all gaskets, o rings, and soak it in kerosene. it will dissolve the varnish if any is present.

also if you have a set of torch tip cleaners, use the next size smaller than what fits in the jets and clean the jets out.

varnish could have flaked off from inside the tank and worked its way through to the carb and plugs it up when a vacuum is present.

just be careful to remove just about everything that's not metal when you soak it in kerosene, kerosene will dissolve gaskets and o rings.

also if it has an air filter, check to see if it needs to be replaced.
