Got the engine warm today, i gave it a few revs. when i rev it a puff of black smoke spews out the exhaust and leaving black marks on the bumper. its a black carbed 202 motor. i just did an oil changed in it and made sure it wasn't over filled, so i can rule out that. would it have something to do with the fuel/air adjustments?
cheers
yer, i sort of thought it might have, as it likes to go through abit of fuel. i know where the adjustment screws are i just don't know where to adjust them to.
i also took the plugs out today, because i was putting the HEI dizzy on. and the plugs were heavily covered in carbon.
