The timing should be set to Top Dead Center (TDC), but you must disconnect the electronic spark advance feature. Unfortunately, I don't know how to disconnect the spark advance. The timing chain is all that can be set. There is no way to set the timing as the distributor is not adjustable.

How do you set the timing on a Mazda b2200?

Ignition timing should be set to 6 deg BTDC, this is done with a timing light. Connect the power leads of you're timing light to the battery and put the pickup clamp over #1 plug wire. Disconnect the vacuum line on the vacuum advance and plug the line so it does not create a vacuum leak. Start the engine and shine the light on the crank pulley to see the timing mark. It should be pointed at 6 deg BTDC. See the attached links on how to install and check you're timing belt. Kyrasis6 Mazdatruckin.com


How do you set the timing on a 76 Chevy 350?

# Disconnect and plug the vacuum line that connects to the vacuum advance diaphragm on the distributor. # Loosen the locking bolt at the base of the distributor that allows it to turn freely, but don't turn it yet. # Connect a good quality timing light, the kind with an EXTERNAL power source, either plugs into the wall outlet or connects to the vehicle battery. # The engine has to be timed close enough to start which requires a little knowledge and experience. # Start the engine and point the timing light at the timing mark on the dampener pulley. # Turn the distributor (where you loosened it) until the timing mark aligns with the appropriate advance mark as specified in the manual. The advance may be slightly different for YOUR altitude. # Once the timing is where you want it, turn off the engine and tighten the distributor lock bolt, then restart the engine to make certain the timing is still right. # Disconnect the timing light and reconnect the vacuum advance line.

What are your preliminary steps to setting the timing on a 1989 Chevy S-10 2.5L and what are the degrees of advance?

AnswerMost of the time, the steps to take to set the timing are on the catalyst sticker under the hood. But first, you must get the vehicle into base timing (usually disconnect a wire from distributor). Remove distributor hold down bolt, hook up timing light to #1 spark plug wire, start engine, and align timing mark (0°) Once this is set, reconnect the wire you had to disconnect for base timing. Timing advance will automatically set itself. if it doesn't, you have a faulty timing advance mechanism on the distributor. You can check timing advance by pointing the timing light at scale (while hooked up to #1 spark plug wire) and rev the motor. Timing marks should move up the scale.On many GM cars and trucks the wire that you disconnect is solid gray in color, it is in the wiring harness on the firewall, the wire has a black plug for separating when doing the timing.
