I was also thinking timing, if all else checks out. Possibly too far advanced?



Which timing, cam or ignition?

I have the ignition timing set at 7 btdc now. My road test told me that there was more lower end grunt (especially in the 1500-2500 range, or so) than before. But, the top end is still the same. It makes power to around 4500-4700 rpm.

I wish I could post pictures, but there doesn't seem to be an easy upload feature. The rotor in the distributor is not quite pointing at #1 with the crank at tdc. It is slight advanced of #1. Not sure why. Is this normal? If I adjust it by one tooth the other way it is about the same distance away from #1, only on the other side.
