Ignition Timing Marks
Hi,
I'm going to be using an ignition timing light for the first time tomorrow and despite all the reading and YouTube watching I've done still have a question
Do you use the TDC or BTDC marks?
Cheers.

Cheers for the link JRT, I've already read it and still have questions.
In the 1.9DG section,if it's out then how do you tell it's out?
My engine isn't starting so I'm checking the timing just to check it''not the reason.

Re: Ignition Timing Marks
To answer your question you use BTDC mark if the strobe is not adjustable
if the strobe has adjustability then set to zero and use BTDC mark or set strobe to 5 degrees BTDC and use TDC mark
Adjustable strobes always catch me out as I forget to zero them. Very dangerous.

Mine's a pain as it defaults to 10°, even if power is interrupted for just a moment. Easily missed! Why-o-why don't they all default to 0???

Mine ( Gunson) has a twidly knob which has no resistance so it gets moved every time you pack it away or sometimes just resting it down.
I set the timing then think that sounds wrong then remember, this happens every time because I don't use it as much as you might.
