If you mounted it your fingers wouldn’t get cold... Cold

Anyway, cool that it runs. May need to play with compression, I would buy a couple liters of Sunoco race fuel if they still have them up your way. I know in Ontario they stupidly merged with Petro-Canada.

VP sells a good octane booster in 1qt cans. Should be available at Canadian Tire or Princess Auto.
