Ted , go to www.4cycle.com , Karting forums , Ohv engines , World Formula , and search for "IKF Tec Rules Conflict ", the info there may help on the ignition rule in the book.
I wish I could " cut and paste " !!!

| You are required to use the stock key and the the timing is taken when magnets leading edge touches the foremost magneto arm. IKF tech says it should read at 24-27 degrees timing (about 27-29 BTDC actual timing). |

Isn't there a minimum width specified for the flywheel key? I've heard of engine builders shaving flywheel keys to meet this minimum so that the timing could be advanced as far as possible.
