Ignition Timing and Vacume
 

Does anyone know what the normal full advance should be set at? I thought it was 30 degrees at 3500 rpm??? Does this sound right?

Also, what about vacume at idle? Does 11 or 12 sound correct?

Thanks!

Correct timing is based on your combo. For naturally aspirated, 14 degrees at vacuum idle is a good starting point, going up from there. As far as full advance, it's all according to what you have, On a midly modifed motor, full advance should be in the ball park of 30-36 degrees

Thanks a lot!

Do you know what the normal vacume draw at idle is though? Does 12 inch sound ok?

Thanks!
