put some good octane in there & (1) set your initial where your cam/eng likes it (2) shorten the slots for 36-38 total (vac adv (if used)disconnected) (3) play w the spring combo so you get a fast a curve as possible but staying just under the pinging point as you run it thru the gears @ WOT on your hottest/driest day (4) hookup the vac adv & add as much of it as it will take without pinging (or missing from too much overall timing) @ PART throttle on your hottest driest day. Get each stage near perfect then the next one(& in order) so that nothing is being left on the table.



But he stated starting problems when he had 36 total? This is usually to short of slots where the
real initial not idle advance is too far ahead for his combo. I like a longer slot to lessen starter kickback and some like shorter slots Oh well tomato tomato?



Unless somebody has already screwed around with the dist, it's not likely that the advance slots are too short - nor is he in to the advance curve at 500 - 550 cranking rpm. Again, leave the vacuum advance disconnected until you have the mechanical advance sorted out. I would be interested to know what the cranking psi compression is?? Is the motor healthy - not pushing lots of oil??
