Q:how do u set ignition timing
A:Adjusting ignition timing is one of the first things that any mechanic learns how to do, and it's one of the most important settings on any engine. If your ignition is "advanced," the spark plug fires before the cylinder reaches the apex of its travel; "retarded" means that it fires afterward. To an extent, more ignition advance will net you better performance and fuel efficiency but will increase emissions and decrease the engine's octane tolerance. It's a fine balancing act, but easy to achieve when you have the right tools. Things You'll Need: *Rag, *Carburetor cleaner, *Green scrubby pad, *Sandpaper, *Timing light, *Basic hand tools. Instructions: 1) Locate the timing marks on your harmonic balancer, the heavy, ring-like device on the back of your crankshaft pulley. The timing marks are generally cast into the surface of the balancer. On some engines, the balancer has an engraved line, and the numbers are on the engine block. 2) Clean the balancer with a rag and carburetor cleaner to remove the grease and dirt, paying special attention to the engraved ignition marks. Fully dry the balancer with a rag and lightly spray the balancer and the numbers with white spray paint. Wait for the paint to dry, then run a piece of sandpaper over the balancer's surface to remove an paint there. Once you do this, the paint in the engraved numbers will remain bright and legible. 3) Disconnect the vacuum line going into your distributor's vacuum advance module (if so equipped) and plug the line with an old bolt or a golf tee. This step is crucial, since leaving the vacuum advance line connected will throw off your initial advance settings. Loosen the distributor hold-down clamp, then snug it up just a bit to hold the distributor in place. 4) Start the engine and bring it up to it's operating temperature, then shut it off along with any lights and electrical appliances in the car. Connect your timing light to the spark plug wire on the No. 1 cylinder. On in-line engines, No. 1 is the forward-most cylinder. On V-configured engines, the No.1 cylinder is usually the driver-side front cylinder. Of notable exception here are Ford's V-8 engines, where No.1 may be on the passenger side. 5) Start the engine and point the timing light at your harmonic balancer. The light will flash in sync with the spark plug firing on that cylinder. If you don't see any markings on the balancer (next to the pointer-indicator on the block) then disconnect the timing light and connect it to the front-most cylinder on the other side. Loosen the hold-down clamp slightly. 6) Note the balancer reading relative to the pointer. On the balancer or engine block you'll see either a zero or the letters "TDC," which stand for "top dead center." Generally speaking, the numbers below that mark are degrees of advance and number above it indicate retard, but your balancer should indicate either way. If you don't know for sure, then turn the distributor a little toward the direction of the vacuum advance module and listen for a rise in engine rpm. This is the direction of ignition advance. 7) Turn the distributor until the degree reading on the balancer matches the amount of advance or retard specified by your manufacturer. You can usually find this information on the emissions tag under your hood. Once the balancer reading lines up with the pointer where you want it, then carefully tighten down the distributor hold-down clamp. Re-check your timing to make sure that you didn't bump the distributor while tightening the clamp. 8) Reconnect your vacuum advance. If you advanced the ignition then your idle will be slightly higher than before; it'll likely be a bit lower if you retarded the timing. If so, then turn the idle adjuster screw on your throttle body or carb to set the idle where you want it.
