Hi mate, you quoted this when you were helping a chap on here set up his timing:
Ignore the intermediate shaft, the marks are almost always a off. The important thing is the dizzy is in the right position, which is set by loosening the clamp bolt and twisting. You need to set the dizzy timing using a timing light, pointed at the flywheel inspection hole after you remove the green bung
On a k-jet car you set the ign timing with the engine idling and the vac line to the dizzy disconnected & plugged. Point the timing gun at the flywheel inspection hole then spin the dizzy until the large diamond BTDC mark lines up, like so:

I have a technician at work setting the timing on my 16v today and he would like to know If the diamond mark is true TDC or 6degreees TDC? The car needs to be set at 6 degrees TDC (correct?) if mine does not have the diamond mark on the flywheel? Also is the mark on the right of the diamond true tdc?
Cheers Tim

zee diamond is 6degrees before TDC, the small punch mark to the right is TDC :)
You might want to confirm the punch mark is correct if there by checking piston #1 is at the top of the bore. May be a replacement flywheel, or someone has bodged it on wrong!
If the TDC mark on flywheel is ok you can use it with one of those funky advance timing lights, program 6 degrees advance into it and line up the punch mark. If your mate is a mechanic he will likely have a proper snapon timing light or similar :)
If the TDC mark is not there you can use the TDC mark on the crank pulley in the same way, there is a notch on it that should line up with an arrow on the inner belt cover. its not quite as accurate but it should be ok.
