I have tried everything to get my 01 banshee 350 to run after top end rebuild. cleaned carbs, new gas n plugs. have adjusted the fuel air screw, now its back firing. it will start for a second if i hold the throttle wide open, then it will idle by pumping the throttle a lil bit then it dies. there is also some gas coming out of the over flow hoses from both carbs more from one, pretty sure the floats are good though. also when it does start one pipe is blowing more smoke than the other. Please help going crazy!!!!
