I struggled yesterday to verify the rev limiter rotors position at TDC after reinstalling distributor. The position of the distributor effects the its orientation. I marked the distributor previous timing position with a scratch but want to verify the rotor as it seems one tooth either way is close. Is the small dot on the wide rev limiter rotor what should line up with the notch on the distributor? I remember the no rev-limiter rotor being more straight forward in terms of lining up with the notch.
This pulley is from a 74, there was no mark for advance 35 degrees before TDC all the timing threads I have research say there should be. I measured with a metric sowing tape 35 mm and put a notch on the outside of the pulley. ??? I presume the marks to the left are for MFI??
I had a couple dramatic backfires hopefully nothing was damaged in the 76 CIS system that I replaced the original 74 set up with, a smoke test revealed major air leaks I was able to install the 6AL MSD box and Pertronix ignitor as this 911 was running previously with no CDI. Upon 1st start up it ran but was stumbling seems off then I could not determine the timing and thought I was a tooth off. May have been 180 degrees off as the timing light registered no marks. Hard on Kauai as there are no 911 experts. I want to make sure I get the number 1 TDC right before I continue.
And advice would be appreciated.
