Hi. Ok, I got the new EngineTec double roller cam and crank gears installed. (Rock auto) I left out the oil slinger as suggested as it did grind on the gear. New problem/question! The engine will only run/idle pretty decent with the timing at about 40 degrees BTDC. This seems like way too much. My Chilton's manual says it should be at 18 BTDC. My timing light just broke so the 40 is a static approx. with the rotor at #1, engine off. Any ideas why the timing has to be so far advanced for it to run? If I retard it, it stalls and won't start. It sounds ok at high rev and idle at this setting. The EngineTec crank gear was a 0 degree setting, which eliminated the EPA 3-degree retard that Ford put in the original crank gear. Vacuum advance was connected during this start-up. Because I had to advance it so much my vacuum advance diaphragm is way off to the left now instead of in front of the distributor like it used to be. Do I need to rotate it a tooth or 2 on the cam with the #1 piston at TDC and rotor at #1 to get it back in the front and make up for the 40 degrees BTDC needed to keep it running?
