    Thanks for the advice everyone.

    The fuel diaphragm may just be the problem. I will check that today. Once the engine is warm if I disconnect the fuel line while the engine is running for like 4 seconds before killing the engine it starts right back up immediately normally 1 pull if I don’t 2-3 pulls.

    The carb also stays dry no fuel oozing out of it when I pump up the fuel bulb I can hear fuel going into the carb then the fuel bulb gets hard to pump like normal and no fuel leaves or leaks out the carb. No fuel oozes out the carb while its running either.

    The spark plugs run clean as and dry when the engine is running they only get wet on the initial start-up. Both plugs get nice and warm once running and engine warms up quick so thermostat is working. The plugs are also new but the old plugs I had in it up to yesterday were running dry and clean looking the were begging to clean up on their own the more I ran the engine the cleaner looking they became.

    To start the engine initially cold I pump up the fuel bulb then disconnect the fuel line from engine set the speed to high speed then pull the rope like 7-10 times fuel actually shoots out the fuel fitting on engine then after like 5 pulls it tries to start but it normally takes a few more pulls.

    Compression seems really good. I also put new plug wires on the engine and it will run very slow especially with the electronic modules it actually has a hard time stopping it idles down so low. The motor also had this problem with the points and condensers installed I forgot to mention that.
