Okay, I will go see what carb it is.
Not to be defensive, but just to set the baseline: Joe ain't just the neighbor. Colorado enduro champ in, oh, probably the sixties. Our best local mechanic for a quarter century. And his son Pat, also a national treasure, had the same Beta until a couple months ago.
So any incongruities in this discussion are mine. I'm having one conversation with the bikes, another with Joe, and another with you-all. And I'm a carpenter, not a motorhead. Thanks for the encouragement.
You'd get along great with Joe.
