Hello, I'm Tan. Welcome to JustAnswer. I'm reviewing your question and will reply momentarily.

Expert:  Tan replied 3 months ago.

Have you checked for spark at the spark plugs when engine won't restart?

Customer: replied 3 months ago.
Has spark all fuel and vac lines replaced Cdi replaced carb cleaned new plugs wires
Expert:  Tan replied 3 months ago.

Does it have spark when the motor quits?

Customer: replied 3 months ago.
Motor doesn't quit runs fine but won't restart after you shut it off until it cools down engine is not overheating
Expert:  Tan replied 3 months ago.

If it won't restart does it have spark?

You either have no fuel or no spark for it to not restart?

Customer: replied 3 months ago.
Any chance it could be the stator
Customer: replied 3 months ago.
Or crank seals
Expert:  Tan replied 3 months ago.

Again I will ask do you have spark when it won't restart? This is the 4th time I have ask this question. We cannot get a diagnosis till you answer my questions.

I can guess all day long as to what it could be. Do you want guesses or a way to fix this motor?

I don't see what crank seals would have to do with an engine that won't restart.

Customer: replied 3 months ago.
Always has spark
Expert:  Tan replied 3 months ago.

Thank you. Then it isn't an ignition issue. Meaning you have a fuel related issue. Once has warmed up do you use the choke to restart?

When engine won't restart squeeze the primer bulb does it get hard or continue to pump?
