actually it might be more than half way, more like 20 degrees.

i retarded the timing a few degrees and my AFR's at 2500 got richer, and as expected at idle they got leaner, about one point. from 12.1 to 13. so i brought it down to 12.5. now my 2500 rpm AFR is 13.8. i am still at 3bar WCP and could raise it up to get the AFR to 14.4, but it seems to run better here. so i will leave it for a while.

now my idle timing is around 10-12 degrees and full advance is abput 3 degrees before the mark.

as for the timing mark. i am not sure if 1mm equals 1degree on the pulley, but it looks like my timing marks is 29mm past Z1. since i have the euro FD head, and i think the euro cars are set to 29 degrees, are the pulleys different and would they have swapped pulleys???

i still have the shims under the vac pot. now that things are a ilttle better, i can re-test some things and hopefully get correct results.

man there was a LOT of heat coming up from the engine that made it hard to adjust the timing. time for new thread.
