simplicty 16 horse

[oldblue1]

my 1991 16 horse simplicty mower is smoking out of the air cleaner.runs rough and dies any ideas.

 

[T.R.K.]

No good ideas. Which engine is in it?

Is there gas in the oil?

Do you have the equipment to do a leak down test and check to see that the valves are sealing?

What is the compression? This may not be a helpful number if the engine has a compression release.

If you disconnect the crankcase breather hose at the air cleaner, does it run better, but smoke there?

Remember, it only lacks 2 years being 30 years old.
