Motor seems to be flooded at all times. It will start but misses and rolls blue smoke. It was a come and go problem at first but now it does it all the time. In fact, it would come and go in an instant. Replaced carburator-no luck. Replaced coil packs-no luck. It has not jumped time. It is a 2-cycle engine with a diaphram type fuel pump which is fixed to the carb. I tried a carb off of an identical engine that I knew was good and it ran the exact same way. I'm convinced its some sort of weak fire.
