I've heard of using JB Weld to limit the advance, but what about the fact that adjusting the vacuum advance with the allen key didn't affect the amount of advance? I don't want to limit the advance down to 10-15° vac advance if something is still wrong with the can. Someone please correct me if I'm wrong, but you are adjusting the amount of vacuum advance with the allen key right? Or is it always the same amount of advance and you are changing the vacuum signal required for the advance to kick in?
