Vacuum advance information and myths

RB,
Pleeeeeeeeeeeease keep posting [ post #38 ]. It shows how ignorant & stupid you are.

I never said everything needs 50* of timing at idle.

I’ve seen many times your claim that if you have over 220 @ .050 you NEED more timing at idle than you can get with just initial timing. And you’ve thrown 50 out there more than once.

I know it’s a crutch because I’ve had to do it on junk I didn’t build.

You ought to get a distributor machine and do some actual testing.
