i sunk my eiger last weekend and pulled it to the house drained and cleaned the air box took carb apart cleaned real good changed the oil several times to clear it up also used marvels mystery oil and sea foam with these changes got everything clear poured the ramaing sea foam in the tank and have absolutely no power at all only like its reving up 1/4 throttle and will only run about 12mph clutches and all is fine but smokes white smoke sometimes a little sometime alot sometimes not at all was wandering what the white smoke was since it's air cooled and why i have no power????

 

Seafoam causes the white smoke. Once all the seafoam is used up, itll stop.
