Ya know, I know a guy who used to run comp cars and gassers WAAAAY back in the day (he's well into his 80s) and he set his timing by lining up his timing mark on the balance at the timing that he wanted, turning the ignition on and moving the distributor until the points (remember them?) sparked. After that, he would move the distributor back-and-forth until the ET slip was happy.

Adjustable advance timing lights are not recommended for use on MSD ignitions. Plenty of information/confirmation out there with a little Goggleing.

MSD sells their own light, both 12v and self powered - or - you can try to find an old Ferret/MSD non-adjustable light - or - you can pick up a mint or NOS Sears/Penske 2138 light, this was sold relabeled by MSD years ago under part #8990. This is what I've used for decades. They are out there.

I've seen people say they've had good results with some of the self-powered lights (Flaming River, etc) available as well, but have no personal experience with them.

Ferret Instruments has gone out of business, who is MSD's supplier for timing lights now? Anyone know? The lights still look like the Ferret models 81 and 84. It would be nice not to pay Holley/MSD's pretty significant price mark-up.
I tried a Flaming River light, I much preferred my old Craftsman.

This looks exactly like the Electronic Specialties, wonder if it's the same light?
