Well, I went and adjusted my timing to 5* BTDC and in the process of doing that they say you should disconnect the vacuum advance before setting the timing. When I reconnect the vacuum advance there is no difference in the timing. I'm pretty sure it is supposed to move almost 13* when the vacuum advance is connected, but I got nothin... Am I doomed to buy a new vacuum advance? <img src="/forums/images/graemlins/barf.gif" alt="" />$$
