30 degrees BTDC at idle is very excessive unless you are checking the timing with the vacuum advance connected to full manifold source at the time.
Your timing (both initial and Total mechanical) is checked and set with the vacuum advance disconnected and plugged.
The Total Mechanical (initial plus the built in mechanical advance) should not exceed 40 degrees. You will see figures above 40 degrees if you have the vacuum advance hooked up when checking.Last edited by Frisco; 04-12-2007 at 06:40 AM.
That's going to be nice, like the color. .
