340 Chugging instead of Reving

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.


You dont have to lock it out if you don’t want to. Just turn a bunch of initial into it and see what happens. You can even drive but BE CAREFUL. You will also be adding to the total.

That way you don’t have to pull the distributor or anything. I like easy when I’m sorting stuff out and leaving the distributor in is easier. And less work.
