What should the timing be set at on a small-block Chevy?
Depending on your cylinder heads, compression ratio, camshaft, and centrifugal advance curve in the distributor, “normal” base timing for a street high-perf small-block Chevy is somewhere in the 12- to 18-degree before top dead center (BTDC) range, with total timing at full centrifugal advance about 34 to 36 degrees
How do I set the ignition timing without a timing light?
to set your base timing without a light, you just turn the motor over in it’s normal direction of rotation until the mark lines up with where you want it.. loosen up the distributor and hook up a spare spark plug to the #1 plug wire.. turn the distributor until it sparks.. tighten down the distributor..
How do you know if your timing is too advanced?
Some things to look out for:
- Engine knocking: Engine knocking occurs when the air-fuel mixture is ignited too soon in the cylinder.
- Decreased fuel economy: The timing of the spark plug is crucial during the ignition process.
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.
What can bad ignition timing cause?
If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power. The ignition timing error is typically caused by damage internally like the pistons or valves inside the engine.
Which way do you turn a Ford distributor to advance timing?
For an initial start, it is recommended that you advance the timing by turning the distributor counter clockwise 10°, and then set the timing by using a timing light.
Will advance timing cause rich?
It doesn’t change how rich or lean the MIXTURE is per se. (How rich or lean the air/fuel charge is that is being introduced to the chamber).
What happens if ignition timing is too advanced?
Advancing the timing means the plug fires earlier in the compression stroke (farther from TDC). Advance is required because the air/fuel mixture does not burn instantly. It takes time for the flame to ignite the all the mixture. However, if the timing is advanced too far, it will cause an Engine Knock.
Which way do you turn the distributor to advance timing on a Chevy 350?
A: Chevy distributors rotate clockwise, so you’d want to turn the distributor counterclockwise to advance the timing. Advancing timing to aid in cold starting will only help if the timing was retarded to begin with.
How do you set total timing?
How is it set?
- Determine your desired total timing.
- Set your Timing Light to your desired total timing.
- Start the engine.
- Rev the engine past the point where your mechanical advance is fully engaged.
- Watch the timing mark on the harmonic balancer using the timing light.
