Bringing total timing in faster will boost your throttle response. Be sure to inspect the balancer to ensure it’s not out of whack before proceeding. If your harmonic balancer is old and the rubber is worn, it’ll throw off your timing reading. However, there’s no universal formula, and you may still need to make some tweaks to the timing to please your engine. That way, you can still double-check timing without timing tape. Patented skip circuitry tests up to 9,990 RPM. Capabilities: Check timing, diagnose a no-spark condition, check for electronic advance and more. Compatible with most import and domestic ignition systems. It’s good practice to mark the location of the total timing number you desire with a notch and some white paint. Innova 3551 Inductive Timing Light offers an entry-level timing light with all the features a weekend mechanic needs. But the reality is that they’re two different processes. Advancing and retarding cam timing sounds similar and can have a seemingly similar impact on throttle response as ignition timing. Do not forget to remove all your tools from the engine when you are finished.īe careful to keep the timing light's wires away from moving parts in the engine bay. Use some type of fender cover so you do not scratch the paint. Turn off your engine, replace the vacuum advance hose, and disconnect the timing light. After re-tightening this fastener, check your timing again to make sure - tightening the distributor may change your timing. Once the timing is correct, re-tighten the distributor hold-down clamp bolt, making sure you do not move the distributor. Continue doing this until the pointer is pointing at the correct degree point as required. Then, check again with your timing light. If it is farther away from the marks, then move the distributor in the opposite direction. Rotate the distributor slightly, then aim your timing light back at the timing marks again.

Start the engine and adjust the idle to the specified rpm. Only loosen it enough so that you can turn the distributor body with some resistance, not enough so that it's loose. Loosen the distributor hold-down clamp by turning its bolt counterclockwise. If it is not, turn the engine off and proceed to the next step to adjust your timing. If the pointer is pointing at the correct mark, you do not need to adjust your timing. Because of this, the timing marks will appear to be standing still. Aim the timing light at the timing marksĪim the timing light at the timing marks, and press the button on the light. Then, on the side of the distributor, disconnect the rubber hose from the vacuum advance and put a piece of duct tape on the end of the hose to seal it off.

If you want, you can use some chalk to mark the timing marks to make them more visible. Now, your timing marks will have a line labeled '0' with marks above and below it, and depending on which way the wheel rotates, you will see the lines before the '0' (BTDC), or after the '0' (ATDC). There is also an 'ATDC.' 'Before Top Dead Center' and 'After Top Dead Center' - top dead center is the point where the piston reaches the highest point in the cylinder and that is when the compression is the greatest. As you can see, it also says something about 'BTDC' for this Ford. All this means is that you want to line up the pointer on the timing light with the 6° timing mark when the engine is idling in gear at 550 rpm. For example, a 1969 Ford 429, it's 6 Degrees BTDC 550 rpm in drive gear - with automatic trans. Your auto's spec or emissions placard sheet should tell you what your timing degree should be. Look to the auto's spec or emissions placard sheet If the feat doesnt meet one of the two parameters, aim-dodging should be assumed. 2: If a character hits or actively deflects the bullet off of a weapon or body part. Rotate the pulley, if necessary, so that you can see the mark. The main ways to tell if a feat is bullet timing or not are: 1: If the character clearly moves out of the path of the bullet after its fired. Locate the timing marks near the lower crankshaft pulley, and the mark on the pulley itself. Clamp the largest clipĬlamp the largest clip (the one with the thickest insulation) around the No. Clamp the black clipĬlamp the black clip to the negative terminal of your car battery. Clamp the red clip on the timing light to the positive terminal of your car battery.
