Hello everyone , welcome to my problem . As the topic states , I have a Banshee with a major problem . It had a top end put on and now you can only start it with starting fluid and then it just raps out . The head has a deep pit on the left side , but both cyls. have 120 psi . I've sprayed everything I can find with carb cleaner and found no vacuum leaks . I've also cleaned the carbs , no help . The throttle slides are down where they should be I think . The T.O.R.S switch was replaced on the right carb because it broke and wedged the throttle open on tha side , not sure how many turns they(screws) should be . I'm not sure if the air screws on the rear of the carbs are set right or not . Could this be the problem ??? If so how many turns out should they be ??? Please help !!! Thanks!!!
