Good hand-held timing light/tach combo.

Gus I have the Snap On light also.Works with my MSD setup.Mine was like 200 bucks years ago.I wonder what they cost now.I still have to make a trip down and drop off my air chisel so you can get a price on rebuilding it.Might be cheaper to get another one.I sure miss it.Rocky

Mine was under 200 when I bought it.Lent it to a guy at work and he melted the lead.Boy was I POed.It was only like a month old.New lead and its been flawless in over 20 years.One reason I keep my box locked even though its home and Im retired.Rocky

Clicked on the Snapon link above and under "specifications" it lists country of origin as CHN. Surely that doesn't mean China right?

I have a Craftsman dial back timing light... seems to work fine with the 6AL. Wish it had a tach, though!

I have a full MSD ignition (6AL, blaster coil, distributor) on my barracuda and I use this timing light with no issues:

Here is their web-site's QA on multiple spark usage:

Since the multiple spark ignition systems are electronic ignitions, I guess their answer is yes.

Hello All! I collect and sell the old, "SEARS PENSKE" timing light's! Non dial back! If you use any other timing light, you need to rev engine past 3,000 rpm to set timing!! Because the MSD ignition fire's the plug, 3 time's in 20 degrees at idle! If your timing light doe's not pick up the first fire your total timing will be off!!! With the dial back and up timing light's they may pick up who now's what signal!!!

I set mine with my SnapOn and its where its supposed to be.My old Craftsman dial back worked on it also.I think the bulb burnt out as its 40 years old now.Rocky

Summit racing advertises the Innova digital timing light as multiple-spark compatible:

On the MSD website, I found this thread on the subject, dating back to November 2011:

It is now July 2014. I bought my timing light in November 2012 and I have never observed my Innova 3568 TL wigging out at low RPM. Maybe they addressed any issues with msd type ignitions at lower RPM? I will call them tomorrow to find out for sure.

Just got off of the phone with Innova support and they said "no, none of our innova products support multiple-spark ignition systems."

Also, their "FAQs" section for the Innova 5568 (as apposed to the 5368 that I have) states "Our timing lights will only work on conventional breaker point, electronic ignition systems, or with DIS (distributorless ignition systems). Some DIS systems are not adjustable. Consult the vehicle's service manual for procedures and specifications before attempting to time vehicles with DIS systems."

Next I called Summit's tech line and asked them why Innova says their lights are not compatible with msd but Summit's website says they are. The tech guy informed me that their advertising department handles that aspect of their websites. He then spent some time to identify a timing light that states in the manufacturer's documentation that it is compatible with msd. The only one he could find was the Flaming River timing light, model FR1001.

I guess I need to buy a different timing light to set my initial timing.
