Has anyone had any problems setting their timing w/ MSD ignition? I was told you have to have a special timing light. Some guys around here have had some problems. Anybody know anything about this?

you should avoid using an advance adjustable timing light with an msd ignition. otherwise everthing is the same.

Yes they don't recommend using the adjustable lights and not all timing lights are capable of reading a capacitive discharge ignition system.

I also haven't heard that before...... I use an advance adjustable Snap-on timing light and haven't had any trouble that I've noticed. I don't use the adj. advance on it for my race car thou......

i used to use our snap-on adjustable timing light too, until i read a tech article from msd (which i think is on their web site).
from memory it was something about inconsistant readings/settings and possible damage to timing light, due to the multiple sparking.

Yikes!! Thanx Rocket. Thats a mighty expensive timing light for me to take a chance on. I won't be using it again on the race car.

The reason I'm on here asking is because some guys down here were having some problems and someone hooked them up w/ some "special" timing light to be used w/ MSD. Something about the freq. MSD puts out and it confuses a regular light. They set it w/ the adj. light and then the special light and it was way off. I've always done the same as you guys and never had a promblem either. It could be a bad light but they said they checked it against a couple lights all being off. When I say off I mean 12-18 degrees. The guys doing this are pretty smart guys so I think they know what they are talking about. It has just had me concerned and I was trying to see if anyone could shed some light on this subject. I am going to borrow that light and check it against mine and I will let you know the details on the light and what happens.

I have the old Snap-on adj. timing light. Knob on the back type. You need to have the calibration checked occasionally with another non adv.adj. light to make sure the degreed dial is really zero when it is on zero then youre Ok. Been using this for years and I heard they can get off cal. mine hasnt(yet). This is the reason MSD says to use a non adj. light.It leaves no room for mistakes. One of the major reasons for timing inconsistancy is the Dampner has spun and your marks are off.A customer had his brand new Proffesional Products dampner do this and he ate a head gasket.Of course it got the head and block too.Stock type dampers will do this if the engine is stopped suddenly like locking up the rear wheels and killing the engine.Check your Dampener and mark it so you can check for slippage.

Most engine builders I talk to don't want to use the adjustable timing lights. Seems too many people adjust them incorrectly.
I use a timing tape to mark my balancer then use a standard timing light from there.
I have checked the timing using both and haven't found a difference.
Of course I mark 0 and 32 degrees with seperate colors to avoid using the wrong mark for my settings
