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.

Itchy's excellent explaination here https://club8090.co.uk/wiki/Pe ... 1.9_Timing" onclick="window.open(this.href);return false; i'd never done mine until a few years ago and it's all pretty easy.

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.

Cheers for that, something else to read

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.

Cheers all

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.

Hi,

Hi,

Does anyone know if the image above is with No1 cylinder at TDC or BTDC?

Cheers
