Hello. My name is Tan.

Have you checked for spark when trying to restart?

The engine has a fuel issue or an ignition issue.

When engine quits pull fuel line off the tank do you have fuel flow?

I had run carb cleaner through the engine yesterday. Drained fuel tank, added new fuel and started up, ran for 20 min. I shut motor off. Then when trying to restart, it will not start. Disconnecting fuel line, plenty of fuel running.

Ok will the engine start now?

Allot of times when you start cleaning the fuel system you knock allot of old fuel residue loose which then gets into the carburetor clogging the jets and ports. Have you removed the fuel valve from the tank and cleaned the filter?

So we need to verify spark to eliminate this as a possible cause.

To check spark you will need a spark gap tester. We have to use tester so we know the strength of the spark.

Here is the tester you need. You can get these at the local auto parts store.

Set the gap at 3/8 and crank engine. Do you have spark?
