I bought a 646 with a vanguard 18 hp. It suddenly started surging. Has anyone had this problem. I see the governor linkage moving back and forth. I wondering if I have a bad coil or does someone know what to check oin the governor?

Get some SeaFoam fuel additive and add some to the fuel several times while running the engine, this may clear up the crud in the carb. If not, check out carb cleaning in Mac's Corner on this group.:cool:
