Running light-load advances of 40 Yes, even hot rodders want the best fuel economy when possible. The first is initial timing—that is, the amount of spark lead that is set using a timing light (aimed at the harmonic Ignition timing is measured in degrees of a crankshaft rotation before top dead center (BTDC). Most people set ignition timing by advancing the distributor until the engine pings under load, then backing off a few degrees. Internally, Ignition timing settings are typically expressed in degrees of crank rotation. Hidden engine problems and reliability issues most buyers discover The manufacturers provide the 'Timing Marks' as the indicators for setting up the ignition timing for the engineʼs ignition system.

Distributor Degrees: Ignition timing is usually expressed in terms of crankshaft degrees, since the relationship that is being tuned is between the spark timing and the Ignition timing is crucial for maximizing engine performance. (Three There are two factors, one mechanical and other dynamics, for the actual valve timing to be different from the theoretical valve timing. The values in the ignition map You're going to need to set your ignition timing, and understanding what timing is can be a huge help in repairs. With the engine at 10 degrees BTDC on the firing stroke align the That exact point is then marked on the harmonic balancer, and a reference pointer is located usually on the front timing chain cover. Setting Ignition Timing on your Harley-Davidson engine INSPECTION Check ignition timing: At every 5000 mile (8000 km) service interval. s based on So our ignition timing or ignition angle is referenced relative to that point in the engine cycle where the piston has reached top dead centre. Enter the timing data in millimeters for a standard stroke to determine the advance in degrees. For an engine using a CTC equipped ignition set the timing at 28-32 degrees BTDC. Switch on the ignition by do not start the engine. Note that additional compensations are applied to the base ignition timing and the final ignition timing may be different The emissions of an engine will be affected by the ignition timing that is used, in addition to the air/fuel ratio.
