But if you truly have a secret 63 engine you need to always put in premium gas. These engines have a tendency to have very high compression and are prone to knocking when using regular fuel.

Thanks, Qwertydude. I wasn't sure what range my stock jet might be in, I'll be sure to take the 75 out of my cart and I'll be sure to include 80, 85, and 90 in there.
I can't be too sure on what my engine is, but it has a 6B near the rear wheel, and it's labeled as "1p39qmb"; either way I'll be sure to continue to only use premium.
Really appreciate the help
