The most common problems would be a weak or no spark OR old bad gas.
Driving through flood water would cause the ignition to fail and stall the engine.
if you press the pedal to much that is what can cause the engine to flood
temp sensor going bad will cause the engine to dump fuel and foul plugs very quickly.
My John Deere snowblower with a 5 horsepower Tecumseh engine takes ( 20 ounces ) which would be .625 of a U.S. quart
Flooding in a 1994 3.1 liter Cutlass engine could be from a faulty fuel pump. The spark plugs may also be fouled.
the temp sensor that reads low will cause the engine to run very rich which is fine when it's cold, but will flood it when warm.
The carburretor float valve is stuck open or the float is punctured/stuck down.
I am trying to upload a manual but need the URL number . Where would it be located on my snowblower
No spark?
Too much fuel. Can be caused by many things.
There probably is but I would need the model number beginning with 143 to look it up. It may be covered by other things, but it should be on top of the engine.
bad injecter, o-rings are bad, need to either rebuild or replace
