1973 T - Timing Mark Correct?

[lespaul]

My owner's manual says proper timing is 5 degrees ATDC. There are two marks on the fan pulley within 5 degrees of each other. I have the timing set with the timing light so that the mark on the LEFT is lined up with the notch on the housing at idle. It seems to run great. Just want to make sure I have the right mark. Can someone confirm?

FYI - Dwell is set for 36.3 degrees, that is as close as I could get to 38 +/- 3.

Thanks

sounds about right to me

Did you set with your vacuum line attached or not?

I think it's supposed to be 5 ATDC with the vacuum line on, and it will be at 0 or 5BTDC with it unattached.

Some may suggest that you don't worry about the idle timing and set your full-advance (high RPM) to wherever you're comfortable (30-35) and as long as it idles reasonably, you're ok.
