What is the correct ignition timing for a Chevy 350?
The timing can vary between 2 and 12 degrees BTDC, the recommended spark plugs are different and even the plug gaps vary. In most cases starting out with 12 degrees of initial advance is about right.
How do you fix improper ignition timing?
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you’ll advance the timing by rotating the distributor counterclockwise, and vice versa.
What happens when engine timing is off?

If your cam timing is off, chances are you’ll know because your car will not be running well, if it’s running at all.
What can bad ignition timing cause?

- Knocking or Pinging.
- Difficult Starting.
- Excessive Engine Heat.
- Increased Fuel Consumption.
- Reduced Power Output.
What should ignition timing be at idle?
Most engines have between 5-20 degrees of ignition advance at idle. This is referred to as initial timing.
How do you time a Chevy 350 without timing light?
How do you time a Chevy 350 without timing light? Any engine that does, you can warm up the engine and with it running, hold the throttle open to about 4000 rpm and advance the timing until it starts to miss, then just back it off slightly and tighten it down. That will put it very close.
Will an engine start if the timing is off?
Engine Won’t Start: If the engine timing belt has broken, it won’t be able to start. You may hear it “engage” as it is trying to start as you turn the key, but because the engine timing belt is what operates the camshaft and crank that turns the engine, it isn’t able to start.

What happens if ignition timing is too advanced?
If the number is lower or after top dead center (ATDC), turn the distributor counterclockwise. Beside above, what happens if ignition timing is too advanced? Symptoms of incorrect ignition timing are poor fuel economy, sluggish acceleration, hard starting, backfiring, or “pinging” or “spark knock”.
Which is the correct definition of ignition timing?
Ignition timing refers to the point at which the spark plugs ignite the fuel within an engine’s cylinder.
What happens when fuel is ignited at the same 10 degree timing?
As the engine rpm increases to 3,000 rpm, the fuel, — still requiring the same time to burn — would never have sufficient time to burn if ignited at the same 10-degree timing. In order to have the same result, the fuel must be ignited much sooner in the compression stroke.
