With a timing light.
To set the timing on a 1984 Chevy Celebrity with the V6 engine: 1. Disconnect the HEI connector so the engine will run in closed loop. 2. Start the engine and use an inductive timing light to check the timing. It should be at 100 before top dead center 3. If the timing is off loosen the clamp at the base of the distributor and turn the distributor so that the timing is set. 4. When you have set the timing tighten the clamp and verify that the timing did not change. If it stayed the same reconnect the HEI connector.
SBC timing should be set at about 6-8 degrees advance with the vacuum disconnected at idle, about 600-800 rpm
how do you set timing on 110cc engine
== == need to set timing on my 1986 corvette after replace hei
You MUST have a engine scanner to set the timing. The timing on that engine is computer controlled.
A 1983 engine doesn't have points, but if you have changed to a points distributor use the same timing settings that were used with the original distributor. if you can time an engine with a hei dist. it's the same way with points. you have to use a timing light, and turn the dist. to retard ,or advance the timing. If the engine has been fitted with a GM type distributor there should be an access door to the side of the distributor cap. Use a "dwell tach" (with the engine running) to set the dwell, then use the timing light to set the timing. If it's not a HEI ignition then it's safe to assume that it's not EFI either so you'll set the timing by loosening the retaining bolt at the base of the distributor, then turn the distributor to align the timing mark with the amount of advance indicated for your altitude. The timing light will cause the mark to appear that the dampener pulley has stopped and you will be able to move the mark as you turn the distributor. NOTE! When setting the timing always remember to disconnect the vacuum line.
You can set the base timing by ear, But to be able to get the check engine light to go out and to set the timing were it is supose to be requires a engine scanner. The computer controlls the timing on that year engine.
Engine timing
That requires an engine scanner to set the timing.
It requires an ENGINE SCANNER to set the ignition timing on that year of engine.
1988 L6: 600rpm- 4*btc with points; 8*btc HEI
That requires an engine scanner to set the timing on that engine. The timing is computer controled.
