check your compression..most times when you get smoke from the ex..it's either oil or gas..if it's gas your burning..this means your carbs are burning to rich..if it's oil..then you will have low compression..at least thats what i've learned in my working on engines for atv's.

yah but its not oil or gas we smelled it so im stummpet

It can only be gas or oil can't be anti freeze cause your air cooled so its on of the two or your packing in the exhaust is burned out but don't think it would smoke unless its oil soaked.

Sure can you can try this method it works on autos take your coil wire off the plug and just rest it on top of the spark plug dont lock it down... start the engine and let it sit there and Idle you have increased the coil's arch therefore making the plug burn hotter to clear off any carbon, you can also remove the air intake hose from the carb start the engine, get a spraybottle with plain water in it and do like a half trigger shot in the carb and increase the idle so it dosen't choke off. BUT YOU HAVE TO BE EXTREMELY CAREFUL!!! YOU CAN DAMAGE THE ENGINE!!! USE A VERY TINY AMOUNT OF WATER!!!! ENOUGH TO CHANGE THE ENGINE'S TONE.

k i try that

Better check its compression just to be sure that the engine is healthy.
