I don't know about the timing problem, but make sure the electrical connector is on the solenoid (very easy to knock of when doing the wires), and that the vacumn lines are on the solenoid/vacumn advance correctly. Check the lines and make sure there on the vac switch under the intake, attached to the water hose. May have pulled one of while doing the tune up. - Shain ----- In Response To ----- Thanks to everyone who replied to my recent posts regarding my issues that I was having after doing a 'tune up'. I'm still having the issues and hunting for a possible vacuum leak. However, does the following scenario ring a bell to anyone as to where my problem may be stemming from?
