If you got 8 in distributer + 20 on crank(initial) you got 28 total currently.
Well again I am not running any vac advance. so how are you coming up with the 36 total? If you got 15 on crank + 21 mechanical you got 36
well i have 20 on idle again if i change it to 10 at idle i still come up with 28 at all in.
If no vac advance you only add what you read on crank plus the factory built in mechanical in distributer . Do you have a degreed balancer or timing tape on balancer? If so rev it up until mark stops,what it reads on balancer is you're total
so yes this i do have a degreed balancer. I don't use the factory built in mechanical advance this is a mallory dist that is locked out at 28. so what you are saying is that is when i am all in "on the rev" i am at 28 regardless of the initial?
Are the weights and springs installed in distributer? If so you are not locked out. If you are locked at 28 it would read 28 on crank regardless of rpm.
So yes weights and springs are installed all in at about 2800 rpm's. guess the question is if my initial "idle timing is 20" what is my all in locked out timing at 28 at all in? 48 or 28?
Ya I was getting stumped there by you saying locked out. Locked out is when you remove the weights and springs and rotate the distributer shaft 180 degrees. Use the dial back and see what the distributer is adding into the total. 8 sounds off. You are using mechanical and initial to get you're total timing.
You won't know until, you figure out what the mechanical is adding to the initial on crank. Say you have 20 mechanical built into distributer and 20 on crank the total would be 40 degrees.
Ok maybe i have the wrong terminology here. Let say a MSD dist has mechanical lock out plate. the dist still has weights and springs so i would assume that the mechanical advance still comes into play. The mallory dist has tabs that you can limit the advance.
