Got some questions on the vac gauge timing procedure. Looked at several archived threads and there seems to be some variations on this.
1) Understand that I'm to loosen the distributor clamp and rotate the body while running to achieve max vacuum. At what RPM should I do this? Some old posts suggest 500 and others 2000.
2) Should I disconnect the vacuum advance before I try this? And if so, I assume I should plug it somehow?
2) See my aforementioned issues with rough running and having to run higher rpms and part choke. Can I make a rough timing adjustment before starting? And what would be the best way to do that?
