Thread: exhaust /Nissan

carbs were fogged before winter and was run Saturday to make sure it would start before spring break .Seams like the exhaust that would run out my prop on the old Johnson . Never seen this on this motor but all I could do was idle so with the idle speed and fogging it seems likely . Your thoughts .

running on the muffs can make them leak black residue from places you never seen before. Usually just out of the normal exhaust places but I have seen a few otherwise. Don't even have to have a decarb in it. Two strokes are pretty nasty out of the water...that's the oil slick behind you on the water you usually don't pay attention too.Plus they run a little different without the back pressure from being submerged.
