I Went to start my ca yesterday. Got it going ok check my timing I set at 18 int. When i ran it up to 36 total my timing marks were 10deg before not at zero When i adjusted my timing gun got it at zero when i reach 39 total. Ran very well shut off restarted started right up. Of coarse didn't run that long. The secondarys will not out any fuel to the rear of the carb not sure why it worked last year i believe. A freind is suppose to bring up a holley 600 see what happens my dist springs should be here today. I really dont want to change the rear gears would cost alot. My vacuum reading at idle was 7 yesterday is was steady.
