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
The engine for the Craftsman snowblower model 427.886640 was manufactured by Tecumseh, a company known for producing small engines. Tecumseh engines were commonly used in various outdoor power equipment during that time. If you need specific details about the engine model or specifications, referring to the snowblower's manual or Tecumseh's documentation would be helpful.
My John Deere snowblower with a 5 horsepower Tecumseh engine takes ( 20 ounces ) which would be .625 of a U.S. quart
temp sensor going bad will cause the engine to dump fuel and foul plugs very quickly.
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.
I am trying to upload a manual but need the URL number . Where would it be located on my snowblower
The carburretor float valve is stuck open or the float is punctured/stuck down.
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.
No spark?
Too much fuel. Can be caused by many things.
