Didn't know they had timing lights during stone age.......lol

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.

Whatever happened to increasing the timing until it showed on the timeslip no gain or you're going slower? Who really cares about the actual number? Get it to crank, idle, and go down the track.

A cheap Sears light or similar to get it fired and close and then tune it.......

If you can't afford a good damper (balancer) then put the timing tape on there. I don't own a dial-back light, never have.

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.

Don't know. Also don't know if they are still made in this hemisphere. They look like the old Ferrets. I still see an old Ferret on ebay occasionally. They usually bring a good price.

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.

From my personal experience, the digital type advance timing lights are the ones I've seen problems with. I have a decades old MAC, dial type advance light I've used with no issues on MSD ignition systems. Still have an old non advance light that I'll occasionally throw on just to verify. Friend of mine had a Snap-on digital advance timing light he used and was having some issues with his engine not running correctly, he asked me one day to borrow my timing light, his timing was off over 20 degrees. He set his timing and took that light out of his trailer.

I've been static timing engines like that for 60 years, except I use the timing light with the trigger held down and turned the distributor until it flashed. Works with all types of battery powered ignition systems. It was usually dead nuts on..........

I remember years ago watching either fuel or blown alcohol guys doing that, but they would use a buzz box or audible continuity tester across the points and rotate the mag until it beeped. Didn't require the ignition to be powered up.

[older racer]

the older sears, model light is161.2134. works excellent. had a racer years ago, used a dial back on his MSD, motor always tried to kick back when starting, used my sears light, his light showed 35 deg, mine showed 50 deg, reset timing with mine, car picked up 2 tenths and 2 MPH. also started easier.
