Just bought a benly 200 off ebay with a carb problem???I have mixed and matched parts off two carbs but still have the problem. If i described the problem as THE REVS HANG ON AFTER BLIPPING THE THROTTLE would that make sense? Today 17.2.10 i have replaced the inlet manifold to rule out any chance of an air leak and that made no difference. Iam sure that the slide is not sticking. can anyone out there help.
