Re: Bucking Slightly at Cruising Speeds

Checking in with an update! Alright, so, after completely losing spark there for a bit, back on the road. (The cause there was oil on the ground wire from the distributor to the vacuum advance, guessing I was careless after cleaning/oil the breather cap and it dripped. Only an incidental find, though). I know now that I've got good blue/white spark at the plugs. Also verified my carb adjustments were accurate, and that linkages were in spec. Went out for a drive a tonight, and really, hard to complain. That bucking sensation is still there for sure (only when it gets to operating temp). To me, seems like the direct drive is going in and cutting out, like it can't hold pressure. No bucking sensation when accelerating up hills or anything like that. Just cruise.

I haven't tried new points/condenser. That's next. I'm gonna start studying the service manual and how to do various pressure checks and see if that reveals anything. Thanks, all!
