Small Block & Big Block Chevy Specific - 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?

Are you sure the plugs wires are on the right plugs? You have the timing leads hooked to the right #1? Obvious questions, but sometimes you just over look stuff.

yes they are all in order

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.

well the thing is i cant even get the line on my ballencer close to my timing plate other wise it cuts out

Your outer ring might have slipped on the hub of the balancer. What you need to do is find top dead center by pulling the #1 plug.

i have allready done that

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?

well when i bought the car it didnt run at all the carb was broke and the manifold was cracked on it and i could send you a vid of how it runs and also my secondaries never open up on my carborator

What kind of carb?

origonally had a holley double pumper took one look at the carb and said eff that cause only half of it was there and stuck a good rodchester brandnew on it

Well. Could be a sloppy chain. But also the mechanical timing in the dist could be stuck open. Make sure your not running a full time vacuum to the dist

hmm the chain is brand new

Wonder if you got it a tooth off? It will still run but poorly. And you can't get it timed.

i had a mechanic stick it on for me
04-18-2011, 07:40 PM
i got it set for the most part

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.

he used a straight edge i watched him do it but i also found that my mechanical advance was frozen so i fixed that problem

Do you have one of those adjustable vac. advance cans on the "dizzy"? You might wanna check that out, it might be advanced really high...
