got the best vacuum signal at 18 degrees BTDC, so that's my starting point, using the 21 degree bushing, giving a total of 39. Stock is 40 degrees , so I'm not too far off as far as that goes.

thanks for information.

by the way, I'm hearing that the screens I'm using are too restrictive ? Any one done a with and without comparison?
