I recently completed a valve job on my H. I did not do anything to the governor. I put everything back together and it started right up - but surges at low idle. At mid throttle or higher it runs perfectly. No surge and plenty of power.
I was thinking that if the idle circuit in the carb was plugged or dirty and not producing a good idle mixture, that may cause the surging. The idle mixture screw seems to have little or no affect. I bounced that off Lurker Carl and he thought that might be a possibility.
Before I tear into the carb again, any ideas, thoughts or suggestions? All would be appreciated. Thanks.
