Couple of updates
Vacuum is at 8 at idle in gear
The mark on the dampner that has the arrows is TDC

With the vacuum advance plugged initial is set at 17*
When I raise the RPM up the mark jumps like crazy
but it comes and goes in the 34 to 36 range

put a bigger squirter in and hesitation seem a bit better

Any ideas on correcting the jumping timing mark??
