there is a wire behind the plastic shroud on the passenger side of the firewall. THE WIRE MUST BE DISCONNECTED BEFORE ANY ADJUSTMENT CAN BE MADE. if you fail to do this step, the adjustment WILL be wrong. the wire is tan with a black stripe. it has to be disconnected before you start the engine. the spec is 0 degrees. again if you fail to do this step it WILL be wrong. then the clamp goes on the front spark plug wire on the drivers side and the battery clamps on the light go black to neative and red to positive. then line up the marks the clamp goes on number one cylinder and while it's running, turn the distributor until the mark lines up on the damper......if ya don't follow this very well.....get help. or you'll end up paying for it later
Actually on a 1995 the wire should be under the dash on the passenger side of the truck
YES! Any time you adjust the timing you should disconnect the vacuum advance.
perhaps crank pulley has slipped from original position
The timing is set by timing marks on the crankshaft pulley. Using a timing light the light will sync with the engine and show if the marks line up properly. To adjust the timing the distributor is turned slightly. There is a clam and bolt under the distributor, loosen these just a bit to be able to move the distributor.
To set the timing on a Yamaha XT500, start by removing the timing inspection plug and using a timing light. Rotate the engine to align the timing mark on the flywheel with the mark on the crankcase. Adjust the ignition timing by loosening the timing plate screws and rotating the plate until the timing light indicates the correct timing advance. Finally, tighten the screws and recheck the timing to ensure it remains accurate.
You dont.
this site takes to long when we are stressed out i just need timing marks for 5.7l Chevy engine Timing mark is located on the balancer using a timing light aim at the balancer and the straight edge inscribed will show up set at about 6 dgrees before TDC
the timing is usually set by adjusting the distributor and using a timing light on the number one cylinder and pointing the light at the harmonic balancer on the bottom of the engine crankshaft pulley,the timing mark on thr balancer should be marked on the correct degree for example 10 degrees before top dead center. as the distributor is turned the timing on the light will adjust to the balancer . to get the correct timing look under your hood for a sticker that has timing and sparkplug gap specs.
To set the timing on a 1996 Nissan 200SX using a timing light, first, ensure the engine is at operating temperature and the ignition timing connector is shorted (usually located near the ECU). With the engine running, point the timing light at the crankshaft pulley to see the timing marks. Adjust the distributor by loosening its bolts and rotating it until the timing mark aligns with the specified degree on the timing scale. Finally, re-tighten the distributor bolts and disconnect the timing connector.
To advance the timing on a 2003 Mazda Miata, you'll need to adjust the ignition timing using a timing light. First, locate the timing mark on the crankshaft pulley and the timing indicator on the engine block. Connect the timing light to the battery and the number one spark plug wire, then start the engine and observe the timing mark while revving the engine slightly. If necessary, adjust the distributor by loosening the hold-down bolt and rotating it to advance the timing, then retighten the bolt and recheck the timing. Always ensure that the engine is at the correct operating temperature before making adjustments.
The is to Bring the engine to TDC ( Top Dead Center ) you can do this by removing the drivers side valve cover and watching the intake valve.. crank over the engine until that rocker arm opens then closes... also there is a timing hash and timing mark on the timing cover, and harmonic balancer. once this is done set the rotor on the distribur so that once it is in the motor it points the Cylinder #1... then install dist cap, then adjust timing using a timing light.... Hope this helped...
Check your timing... it sounds like it's too advanced. As far as I know, you tilt your rotor to change it (using a timing light to measure off the timing belt) or just use premium gasoline (the rumor is that it detonates slower).
If the engine is EFI you must unplug the 4 wire plug behind the distributor before starting. Then rotate the distributor while using a timing light to the correct position. If the engine is NON EFI then you must unplug the vaccum line from the distributor and adjust the same way. You should plug the line off to avoid a high idle situation as well..
