Gentlemen, the folks who helped me last week.... I tried the compression check again and have the following readings: 8-133, 6-135, 4-133, 2-132, 1-138, 3-132, 5-140, 7-133. It took awhile to get that high though. Certainly wasn't fast. Also, my vac gauge readings were 15-20 main port in front of carb jumpy readings (vac leak?), vacuum advance to distributor 0 at idle and steady eddy on dial as you increased the throttle. Got to a max of 20 and steady at a high rpm. Back port 13/14 (air cleaner port) and fairly steady. My timing is set at 13 degrees tdc at a slightly high idle. Any thoughts on jumpy vac readings and compression readings would be greatly appreciated.
