smoking
 

ok this has been a week, two scooters giving me all they have! one is fixed now onto this problem. this scooter was smoking bad. I put in a new piston and rings. no change! replaced cylinder, no change. changed the head and no change. went on to drain the gas out and replaced with fresh 93oct. gasoline, still smoking!? what could i be missing? it is blue smoke. and smells of burning oil. this is a taotao 49cc no mods thanks for anything you can come up with!

Sounds lean check you're sparkplug to be sure

I'd be checking the crankcase ventilation and see if the problem might be something from that, maybe not vented properly or a missing baffle or filter somewhere in the crankcase venting system? Could it be possible to be over filled with oil or the oil diluted with gasoline?

Rosco, good idea! I will do just that! thanks. I will let the outcome be known.

wow! i drained the oil to just under the matting on the dip stick maybe an half ounce and no more smoking!! unbelievable! thanks for the help!!!
