Has anyone heard of setting your timing like this. I just purchased a rebuilt carburetor from Pony Carburetors. They suggested setting your timing without using a timing light. Advance your distributor until you hear maximum rpm, then set your idle to 700 rpm then adjust idle mixture, take it for a ride and if it pings back off until ping is gone. I did it and the engine seems to run good but when I checked it with a timing light to see where it was at it was at 25 degree. Does anybody have opinions about this and is it safe on the engine. Thanks ed

Jon from Pony Carbs swears by this method, his reasoning is that you can't trust the timing marks on the harmonic balancer, and this method is giving you what the engine supposedly wants.I understand his theory, but I'm skeptical.

That's the ONLY way I could time my car right. I did it by having it in D, on an incline with the back chocked, and retarded it till it started to die, advanced it to good idle, and screwed it down. Starts hot, never pings, and runs less than 180* with the fan, on 115 degree days. I think 91 octane made a BIG difference too, because after I started using it, I retarded it some more.------------------
