Recommended Posts

Thumpster only runs with choke on and revs high. basic carby settings please help. I have had air/fuel mix set at 2.5 turns to 4 turns and have the needle clip settings at lowest as it only seems to want to run there. Choke operates at half to full. Bike will not run at choke off. Bowl is full of fuel although not overflowing. Bike seems to be starving as revs are a bit eratic. Answers please.

is there anyway there could be a loose gear clamp after the carb or loose head bolt.. sounds like there may be a leak after the carburator making it run lean by air getting in.. just a thought. try this start it up and get a can of brake clean and spray where air would be able to get in. the idle should come down if you spray in the area where its getting in the engine
