Ok, I wish to understand completely the relationship between timing and the low speed air mixture screw adjustment on my 350 sbc. This is what I am doing, and what I have always done. I have a bog I would like to workout. Is this correct?
By the numbers;
1. Lock centrifugal advance weights in full advance.
2. Plug vacuum advance vacuum line.
3. With warm motor running at 2000 rpm, use Advance timing light to adjust all in timing @ 32 degrees.
4. Adjust idle linkage screw to allow motor to now idle at 850 rpm and set air mixture screws for highest vacuum.
5. If idle after air mixture screw adjustment climbs, close linkage idle screw to recover 850 rpm and continue to adjust air mixture screws for max vacuum.
6. unlock centrifugal weights & return vacuum advance to operation.
7. Use advance timing light to check maximum total advance and make note of what rpm range this occurs. Get all the timing in by 2000 rpm using necessary springs & weights.
Is this the way it is done?
What if my motor is difficult to turn over when starting because of too much initial advance timing?
I hate breaking the nose off of starters!
Thanks guys.
