Timing Lights with advance any good?

Cambodian Tire? LMFAO! :cheers:

To check for total all in, rev it up to where all in should be, and dial in the light till you see zero on the damper and read the dial (or LED readout).

thanks thats what I thought but the chinese instructions keep telling me to zero the light which is only going to tell me how much advance I have , which I already know, I have the blue bushing in my MSD dizzy which is 21 degrees , maybe I should drop that to the 18 degree black bushing
