single carb........
do you have a line going from the crankcase to the carb or airfilter? if so, what is happening is that the oil vapor is being ingested into the combustion chamber, oil vapor displaces air and does not burn...so you have a crappy air/fuel ratio if the crankcase does not connect to the intake one way or another, you need to get a puke tank and a larger diameter hose to relieve the pressure....seems like an odd thing to be happening, but who knows??? |
