Scratch that, number one plug is at 4 o'clock right now.
I disconnected the vacuum advance but did not plug anything. Its hard because I have the stainless steel vacuum advance line and its hard to get on and off as well as turn the distributor with that on there. I hate to bend it every time I set the timing.You may have it too far advanced for warm starting, even though it runs better.
Are you disconnecting the vacuum advance and plugging the hose when checking timing? It is essential that you do that.
If you didn't remove the dizzy, then the no. 1 you had is the one you need.Meaning the number one plug on the distributor should be at 7 o'clock but mine is more like at 10 or 11.
