How do you adjust the carburetor on a spirit 825 4 cycle Tecumseh engine two stage snowblower. For the engine to run right the choke has to be on all the way. Is it running lean or too rich?

In: Lawn Mowers and Garden Tools [Edit categories]

Answer:

if you must have the choke closed to run, you might want to check the carburetor first. It could be a result of a cracked diaphragm or any single or combination of several reasons you might have this problem... timing, fuel/air mix , jets, (carb) cracked intake manifold, even a bad plug could affect it. I would start with carburetion and make sure the carb is clean, inside and out.

Running on closed choke indicates a lean running condition. The initial adjustment is 1 1/2 turns out from closed on the main jet screw and 1 turn out from closed for the idle mix. Lean running could indicate plugged carb jets, an air leak past the intake manifold or engine valves not seating properly.
