What is the advance curve for a GT6 +? What is the maximum advance it
gets? At what RPM is it maximum advance reached? I am fighting the
timing on my GT6. When I set it to the book setting 4 ATDC the car
runs poorly. The more I advance it the better it runs. However, if I
set it to about 4 BTDC I get a nasty knocking at high revs. The best
setting I have found without knocking is at TDC. It also looks like
my vacuum advance/retard is not functional. Can anyone provide some
info on the above questions?
Thanks in advance
