So if my carb is gettn to much air and not enough fuel ...can i adjust it by taking the diaphragm cover off and raise or lower the jet needle?

It depends at what stage you are starving for gas. The needle affects mid range. You should do a plug chop at 1/4 1/2 and 3/4 throttle.

yes about 1/3 throttle it seems like its starving for gas...i just bought the new carb...i do see a adjustment screw on the bottom side of the carb...it would be hard to adjust if that has anything to do with the air and gas....but was told under the top cover there is a needle valve that can be adjusted...right now i have the breather intake hole closed off a little just so it would run someway decent but i shouldnt have to do that..ideals fine though

Disregard, I merged your 2 carb threads into this one, since they are the same topic. :wink:
