This is not a reliable method and can depend on the earth and type of plug. There is no easy way to see or hear when the black trigger is in the firing position with the red module that compares with the contact points just opening.Ī spare spark plug can be used fitted to the end of No1 lead, resting on the engine with a good earth, the static timing position can therefore be checked when the engine is turned over by hand. We can offer strobe timing lights that are very easy to use. Setting the timing dynamically is recommended once you have fitted one of our electronic kits. However because each distributor is different due to manufacturing tolerances, the base plate with the module firing position set as near as possible to the same position as the points were, the distributor will possibly have to be turned +/- 5 degrees from where it was clamped with points. The electronic ignition module has been designed and fitted to the base plate so it can be easily fitted in place of the points. It is always good practice before removing the old distributor from the engine or removing the points to fit the electronic kit to turn the engine to TDC No1 position and confirm the position of the rotor arm that should align with No1 plug lead.
Ignition timing how to#
You can find out how to do that with a Powerspark Timing Light here. The electronic kit ignition timing setting needs adjusting using a strobe light.
Basically the static setting is inaccurate.Īnybody who uses a strobe and dyno knows that the static factory setting just a guide for the average engine, and since engines vary and wear, each engine must be optimized by dynamic setting. However when you start it up and check with a strobe you may find its actually set at 4 degrees or anything +/- 2 or 3 degrees, because the mark alignment is a guess and the distributor when its turning gives a different setting at idle, when the engine is ticking over. The distributor will be set at say 2 degrees or so you think. If the engine has been turned and is stationary at this position all you have to do is turn the distributor until the points just open, you can use a light or watch for the small spark at the contact points. It’s a guess especially if you can’t get your head directly above the pointer, like below, to line them up accurately. So looking below at the photograph (remember the pulley rotates clockwise so it’s gone past the timing alignment pin 10 and 5 and you can see the setting is between 5 and TDC ) say 2 degrees. The marks are shown below “The timing Alignment pin” is the pointer on the engine and the white marks 5 TDC 5 10 15 etc are on the pulley. Static timing is done with the ignition ON, the engine is turned by hand to the static setting using the timing pointer on the engine and a mark on the crankshaft pulley on most engines and stopped in this position. The first point is to understand the static method of setting the ignition see below….
