Default Flywheel Timing Marks Missing

Hi

The flywheel on my Lister D has been skimmed sometime in it's life, consequently the TDC and timing (lightening bolt) marks are missing. Can anyone remind me of the formula for calculating the 20 degree timing position using the circumference measurement of the flywheel, I had this once but for the life of me I can't find it.

I have found TDC and marked this on the flywheel.

Thanks

Martyn

The key is either at the top or bottom for TDC, I am sure a search on here would provide the info.

Just had a check,

snip, If it helps TDC or top dead centre can be found easily by turning the flywheel against compresion .
When you feel compression and the flywheel keyway is at the bottom you have TDC
