Hello, my name is Justin. I am currently finishing a 1971 roadster and am having issues getting the bike idle down after being revved. The bike starts and idles great but when I hold the throttle for 2-3 seconds the bike revs for 8-12 seconds. Originally, this was only occurring when the bike was warm but after rebuilding the carb it started to happen even with the bike cold. It is worth mentioning that the bike has less than a 100 miles on it since its rebuild.
My first thought was that I had an air leak but I have had no luck finding one. I have tried spraying the motor down with both carb cleaner and starter fluid when running but I didn't have any change in RPMs. Next, I tried rebuilding the carb (single VM34) but it made the issue worse. I believe I may have made a mistake reassembling the floats which I will double check tomorrow. Any suggestions on what to try next?
