What timing light do you use?
 

Tried a light from auto parts store which gave inconsistent readings so I junked it. Bought a Sears light with the adjustable timing advance knob. Last weekend the Sears light intermittently worked and didn't work (light would not light at times) which led me on a wild goose chase. What timing lights do you have success with???

I use an actron adjustable that i got at auto zone or someplace like that no problems to date.

Do you have a MSD SYSTEM?

I've got a Snap On digital tach/advance light.

No, I do not have MSD but I do have Crane HI-6M's. Does that make a difference over stock ignition with timing lights?

nah, i use a cheapo and it works fine with my hi-6m's

I use a Snap-On digital retard light. Works fine with my MSD.

Me too. I first bought a cheapo, it never worked at all, and they would not even allow it to be returned. I borrowed a Snap-on, and it is worth the $ for its features and reliability. Its tach is awesome, along with its adv/retard function with memory

TS,

MSD says to absolutely not use a "dial back" type light on thier ignitions. Apparently the multiple sparks at low rpms drive the lights crazy ? I know plenty of guys that say they use them with MSD's, but also have first hand experience where a dial back light, and a Snap On digital light were both close to 20 degrees off compared to a non dial back light :( So who is to know which one is reading correct ? I have an ancient Sun 7501 that has served me well for many years. You can still find them on E-bay for $30 or so. MSD also has thier own light and they also recommend the Sears light.
