The two setups I have had this carb on were the same block, one was 30 over and the next was 60 over. The factory jet size was fine for both. this current engine is a stock one with stock heads and it doesn`t make any sense to me to make the jets bigger on a lesser setup.

When I measure clockwise on the damper to make the 35.5 degree mark, where will I view this from ? Would it be the usual place on the timing cover, with my head pressed up against the firewall and my face on the battery in order to see the factory timing mark reference spot? And IF I would view this 35.5 degree mark on the factory location on the timing cover, should it show up at zero? Or somewhere else, like 10 or 8 or whatever BTDC ???


I am going to go try to adjust the vac advance setting by turning it clockwise a couple turns to make it advance at lover vacuum and see what happens to the surging as well as the shitty acceleration and I`ll check back here after a bit.


Thanks for all the tips and advise, you guys are saving my ass right now.
