The timing was fine, and carb jets were not blocked. It turns out there was a n air leak between carb snd head. Boy, those o rings are hard to find.

Erodes electrode on CB77Took a nice ride up the Angeles Crest yesterday. When I checked the plugs back home, I noticed the right plug was dead white and no electrode above the ceramic.

In short, he says to set the floats so that the bottom of the floats are lined up with the bottom of the main j...
Re: Engine seizure/advance repairTim, Yes indeed, the engine response has been transformed by your rebuild. I can now detect some small adjustments needed to carburetion which were previously masked. And I could not hear any additional noise. I admit I was surprised at the violence needed to remove the sprocket. I don't like hammer...
