Before you try anything complicated. Unbolt the carb, and remove the gasket
between the carb and the engine. Put on a light coating of Permatex IIB Non
Hardening (yes, sold at Walmart, in the auto section). Give great effort,
not to get that black stuff on your self or clothing. If so, comes off with
alcohol dry gas. Tecumseh gaskets go bad, and then you get air coming in
after the carb, so the engine runs lean.

I bought a Snapper Snowblower model I 524 or 5240 (it says both), at an
auction. It runs, but wont stay running unless I keep it about 2/3
choked. It has a Tecumseh 5HP engine. I dont see any fuel filter, but
have not yet removed the cover over the carb. My guess is that it needs
to have the carb adjusted or rebuilt. I'd like to begin with adjusting
it, but need to know which screws are for what, and a starting setting.
I looked online and found a downloadable user manual, but cant seem to
locate a repair manual. Anyone know where I might find one, or know how
to set the carb adjustments?
