Manifold Vacuum Advance what am I not getting?

You need to step back , take a deep breath and cover the basics again . Check the TDC mark on balancer , set dizzy manual to 17-20* , pull carb and check transfer slot opening ( .025ish …. ). . Probably needs work on idle air bleeds .
Sounds right … Turk is giving me good guidance to visit the balancer checking the advance of the motor.

Ive been reading about making sure the transfer slot is like 1/16 no more at idle. The way I understand this is that if there is too much transfer slot opening it will not allow enough flow to the pilot idle path down the emulsion tube/path. Is that what you’re thinking?

I was going to look at the carb after I got it to a point I can run it. Looks now maybe the initial advance is too high at 42°. I e just had it hammered in my head to give the motor what it wants and was using vacuum as part of the process. When is too much I don’t know. Some have said my motor could want as much as 50°???..??
