Maybe, it depends on the year make and model.
how do you set timing on 110cc engine
You can not set the timing with a timing light on that year engine. The timing is controlled by the PCM./ Power train control module. You must have an oBD2 engine scanner to set the timing. If the timing is off then the check engine light will be on.If you have not removed the distributor are moved it around for any reason then the engine timing is correct already. No need to adjust it. Computer does it.
To set the ignition timing on a 1997 Volkswagen Cabrio with a 2.0L engine, first, ensure the engine is at operating temperature and then turn it off. Disconnect the timing connector (usually a green wire) to enable the timing to be set at base timing. Use a timing light to check the timing mark on the crankshaft pulley against the timing scale on the engine. Adjust the distributor until the timing mark aligns with the specified timing (typically around 0 degrees BTDC for this engine). Once set, reconnect the timing connector.
engine idle set too high or the timing is off and needs reset.
You MUST have a engine scanner to set the timing. The timing on that engine is computer controlled.
First place there is no need to set the timing if the distributor has not been moved. And there is no wire to unhook.The ignition timing is controled by the ECM / engine control module. If the timing is off you will have a check engine light on. If the light is not on, then the timing is correct. No need to bother, The computer is taking care of it.You have to have a OBD II engine scanner to set the timing.
Unless you have had the timing belt off or it has broken the timing should still be correct. The way you set the timing is by taking the timing belt off and lining up the timing marks and put the belt back on. I added a link to a text how-to for setting the timing on the Zetec engine. -ZX2Fast
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.
To set the engine timing on a 4-cylinder engine, first, ensure the engine is off and cool. Remove any necessary covers to access the timing marks on the crankshaft and camshaft. Rotate the crankshaft to align the timing marks to the manufacturer’s specifications, typically found in the service manual. Once aligned, adjust the distributor or ignition timing as needed, using a timing light to verify that the timing is set correctly at the specified RPM.
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.
That refers to engine timing. To set the timing on that year engine you MUST have a engine scanner to set the timing because it is computer controlled. A timing light will not work. The cam and crank sensors MUST be in correlation with each other. You probley have a bad cam are crank sensor if you are having starting and running problems. Only if the engine code is camshaft to crankshaft correlation. If you have removed are moved the distributor in any way then that will also give you the same code. Just have the timing set to specs and clear the codes.
You cannot set the timing as it is all under computer control.The timing is controlled by the computer. Cannot check timing. Suspect timing is off, cam sensor, crank sensor, worn timing chain, bad pcm.
