Can you provide the model and spec number from your engine so that I can better assist you? Do you have a volt meter in order to do a couple of checks if needed?

Can you tell me if your engine has a fuel solenoid valve on the carburetor? If it does there will be a wire going to the bottom of the carburetor, I can't tell just looking at a parts diagram of your engine. Also, do you know if you have Smart Spark ignition? If you do there will be a black box on the starter side of the engine it is about 2" X 2 1/2".

It does have a fuel filter night shut off and it does magnetize but there is not a smart spark ignition

We need to know if you are still getting voltage to the fuel solenoid on the carburetor once the engine is started and the key released to the run position. If you can get your tester inline with the wire going to the fuel solenoid then start the engine and release the key and see if you have constant steady voltage coming to the solenoid through the whole process.
