MSD Disappointment ??

What speed? It barely turns over. When I re curved it I used a light spring from (Mr Gasket ) kit? Left the lighter of the two stock springs alone. My timing is set at 8' BTDC total at 36' I don't use the vac can as it causes detonation? Street car but ran a 11.7 1/4 mile on Nostalia Day last year with it with a 323 gear found out when I got home the secondaries were only opening 3/4 of the way. turns out I was missing the small bracket that holds the cable back an inch that I have since fixed.
But I value your opinion and will look into that as well .

You need to find someone local to you with a distributor machine and get it tested. You cant always see how much timing you are pulling while cranking with a timing light.

What you can do is put your timing light on and get the engine nice and warm. Then turn the idle down as slow as you can and then see how much timing you have.

Also, you may have an issue with your mechanical advance not quite returning back to fully closed when you turn the engine off, which would mean at cranking you are getting more timing that you need.
