Timing Lights
There has been a couple of posts recently about using timing lights .I would like to buy a light with dial back and built in tach that WILL work on my v8 with stock ign and on my model a with pertronics ign . I have a timing light with dial back similar to the one summit racing sells, works well but no tach. I also have a Innova 3568, the strobe works, but the tach and timing advance control are all over the place. The tach on my Uni-t ut107 multi meter will not give accurate readings either. The new modern equipment does not does not appear work on old ignition systems, to much electro magnetic interferance ? Any suggestions ?

Re: Timing Lights
I've always used my Mac TL86 dial back, connected to a spare 12v battery and the strobe is nice & bright. My latest tune-up ended up at 8*btdc, 475rpm.
I then adjust the idle for smoothest running in gear. All stock ignition. Have never had a pre-ignition problem using modern e-free 89 octane. Bob

Re: Timing Lights
I know Snap-On makes a dial back timing light with tach, but probably costs a small fortune.
