Hi Sparker,

Generally surging or hunting as it's sometimes known as is commonly related to air leakage which will force the governor back and forth.

I guess most of us felt that due to you doing multiple carby removals & installs then that part of it was sound and not causing issues, how wrong we can sometimes be without having the actual item in front of us to physically look at and touch. It will catch the most experienced out from time to time. As I always say, wherever there's an assumption there generally a screw up. I normally substitute the "screw up" word for something else. I'm sure you'll know what that word is.

Anyway glad the issue has been solved with no major outlay.

Cheers,
BB.

PS. Maybe you might want to solve my GCV-160 issues LOL !

I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
