I understand how the reverse polarity magnet triggers the board to start the sequence. It was just hard to grasp at first during the phone conversation.

You could always use a supercharger on it and quit fooling around.
If the gas fired Saito radials can run on 15:1 (6.2%) oil, the alcohol version will get a lot more oil at 10:1. (9%) Especially considering 40% more fuel by A/F ratio. 9% /6.2% x 1.4 = twice the lube available.
