I got this motor 3 years ago on ebay out of Alabama. Model # 217-588751, serial # 48 006884. I've had a lot of fun with this stupid thing, but it hates going from fast to slow. It just dies, then it's hard to start. I recently put a red Atom Computer Ignition module on it. Ran great in the can, took me a mile up the river and cratered. Turned out to be the flapper gasket, which I keep in stock at the house. Replaced the flapper and the thicker black gasket that goes under it, fuel pump element looks good under the magnifying glass. ran great in the can, took it to the drink. Got into some weeds, loaded the motor, which died, then absolutely would not restart. This the same problem it's always had, just worse now with new gaskets. When it dies, it has to sit for 40 minutes before it'll light off and run again. What am I missing here, people?
