Thread: MSD 6al timing light question

I have an msd 6al ignition box on my 73 nova, my current timing light (an Equus inductive timing light) reads a higher timing then what is set. Can anyone suggest a timing light that will read accurately and doesn’t cost an arm and a leg?

MSD suggested the sears timing light. I'v used it for years.

462" Buick with Mallory Unilite vac adv distributor and MSD 6AL.

My Sears Penske timing light (standard model) reads right on as confirmed by static timing the engine.

I tried a Sears Penske dial-back style timing light and it read 20 degrees off - I think on the retard side, but don't quote me.

I've mentioned this on other boards and the replies have been that some dial-back lights don't read right and others do.

The dial-backs are nice, but a degreed balancer - which I now have - or a timing tape will do it.

I agree I tried using the dial back timing lights on my MSD and when I use it the timing jumps all over the place when I dial it back. When I put it on zero it works just fine. I think those multiple sparks mess the light up when using dial back.
