Hey everyone,
On my 69 GMC 2500, it seems as though the valves are adjusted wrong, almost seems like they are too tight. The truck has a hard skip to it, doesn't misfire, but runs rough and occasionally pops through the intake. I have to check the timing as well to make sure it is not that, but I was wondering if anybody knows what the specs are for the valve adjustments, and where I could get the appropriate set of feeler gauges to adjust them? The reason I am suspecting the valves is that the motor is a fresh rebuild, and the PO said it ran fine, but he adjusted the valves and only drove it about 1 mile back to his house and never drove it again before I purchased it, and I picked up on this problem when I purchased it. I have a video of it running in my build thread, but Ill include it here for simplicity if that helps. Cant really hear much due to lack of exhaust.
