 PD36 Surging at High RPM
My engine is surging at 4350 rpm (topped out) unloaded . The surge is short and quick. It doesn't show up on the tiny tach. Any ideas? Thanks in advance.

 Re: PD36 Surging at High RPM
You runnin stock carb with govenor? If so, your govenor spring is probably worn causing the surging.

Yep, swap your spring out to a stronger one.
You are bumping the gov.
