timing problem okay so hears the low down i have a 1984 camaro with a small block 350 i cant get my timing at all correct just before i get to twelve degrees the engine will cut out any idea on what i could do to solve that?
relatively speaking, for idle, more timing leaner mixture, less timing richer mixture.
if you're advancing timing from 6 deg BTDC to 8... to 10... and to 12 dBTDC and it cuts out that can be from too rich a mixture, it's igniting too soon, creating too much cylinder pressure before piston gets to TDC and engine stalls. Simple correction is lean out the idle mixture. This is assuming you don't have other problems causing it... bad valves seats, poor compression, or improper lifter preload.

Might be very weak valve springs. If you already checked all the obvious, time to do a compression and leak down check on it. Or maybe your timing chain jumped a tooth. How many miles are on it? How does it exactly run? Did this just happen all the sudden or did it get gradually worse? Have you tried a different timing light?

Mechanics can still make mistakes no matter how many they put on! If he just eyeballed it, it's possible he got it a tooth off. If he used a straight edge to line it up, then we need to start looking elsewhere.
