Hi All
I'm reasonably happy with the timing on the RK but I would like to check the dynamic timing using a strobe light.
So two questions.
Where is the best place at the front of the engine to mark the tdc? (Its a pain having to remove the starter and housing every time I want to check the timing)
Does anyone know of a strobe light that works entirely on 6 volts? (I guess all will work on 6 volts as long as they are powered from a 12V battery?)
Thanks in advance
Howard

Just double checking R. And only cos it says in the blurb "suitable for all 12 volt ignition systems" OK for me?
Best regards. Peter.
And just for those of us like me that have never done it, is it' undo the clamp and adjust by turning the dissy a little each way till it sounds right' and whilst the engine is running? Or do you stop engine and start each time you adjust. OK Might sound dumb and if you don't know the answer then ask someone who does. And R. No one better.

The strobe is useful for observing that the auto advance works, where appropriate.
I have driven my strobe off a 12v battery with the earth (only) on the battery, joined to the earth of the car. The car is using a 6v battery.

Peter,
you need to have the engine running to use the strobe.
If your car is running well, and you are not certain of how adjustment works, I would leave it until you have someone beside who does.

You can check any ignition timing with a strobe that has an HT lead pickup, magneto, coil, self generating as m/cycle types, as its only sensing the HT you just connect the strobe to a 12v battery. Turn distributor in direction of rotation to retard opposite to advance if your distributor slips
in the clamp it retards the ignition due to the direction of rotation.

Along with compression gauges, strobes only became really fashionable when crankhandles disappeared. Older strobes are powered entirely by the spark . I have used on lawnmowers.
