This motor seems to be somewhat cold blooded during initial startup. After cranking and choking for few seconds it will finally start. Once it has cleaned itself out, it will idle just fine. I can go to wide open throttle and it planes out the boat and sounds like a new motor. After about five minutes or so at full speed and backing off of the throttle, the motor misses a few times and then stalls. It will not restart or if it does, it will only run for a couple of seconds before dying out again. It will start the next day exactly the same way. Carbs have been removed and cleaned thoroughly. Distributor and wires checked and cleaned. Electrical terminations have also been checked over. I think it is heat related in some way. Does this sound like a typical symptom or trait for these engines. I am more familiar with Evinrudes and Johnsons. Any help would be appreciated.
