how to set timing - mallory mechanical advance on '74 1.8 Options

[h16]

I need to set ignition timing on a '74 1.8 that has a mallory dual-points mech adv distributor. Model # of mallory distrib is 2354101, in case it matters to someone.

Anybody have tips on how to set timing on this setup, assuming the rest of the engine is basically stock?

Prior to any attempts to set timing, I plan to replace both sets of points, condenser, and adjust the dwell.

Thanks in advance for any help

Do you know the advance curve set up in the distributor? I think Raby used to say something about pink and gray springs, but I'm not hands-on familiar with what any of that really means.

A first approximation would be to hope that the curve is close, and set it for about 5 BTDC at idle. You could instead try for 30 degrees at 3500 RPM, and let the idle fall where it falls.

To do it right, you'll need a dyno. That will help you find the timing that the motor actually likes the best.
