or go by the book - 17  degrees BTDC.
What timing light have you got that runs to 10000? Mine shuts down WAY before that.

Luke,
I only have a basic timing light though I do know of someone who has a very good one that might still operate at 10,000rpm. Will try to get it and see what mine is running at. For now I will set it at around about 1.2 mm as suggested by "Lozza"

Thanks for the replies
