Later today I expect to have time to work on it again. Locking out the distributor seems to be a popular suggestion and I agree, it will remove another variable of the curve coming into effect. I have never locked a distributor before but when I disassembled it to set the mechanical advance, I see there are two set screws on the outer housing that seem to be used for locking the position. Since the current mechanical advance is set at 24, do I need to change that internally to 32, then lock it? Or can the lock screws be turned in and adjust the dist to 32 with a timing light.
