Cap and rotor are brand new. When I first got it there was a bucking problem that I couldn't diagnose. My local shop figured out it was the distro and changed it and the cap. This was a month ago.
This time I also had them adjust the timing since I was out of town.
I was thinking weak spark as well but when I tested the spark it was a white blue color. Also one of the reasons a guy on here calls me "sparky" :(
This morning I went to start it up, started instantly, was on the choke and fast idle, but it was idling about 800, crapily. I let it sit there and idle and about a in minute the idle slowly started to pick up to the fast idle setting of 1300. The exhaust was a light white.
I'm just trying to provide any piece of info I can. Maybe it all connects for someone and can suggest something.
The next easy thing to try is to replace the carb jets and rods as well as the spark plug wires. But I am just guessing at this point.
