    The guy I bought the cart from said 20:1, and I talked to a repair shop here and they said 50:1, so who do I believe? The shop was actually trying to sell me some high end oil that was 100:1. So what would be the best option?

    the 20:1 was the old days when they used engine oil, 50:1 is to lean for a engine that gets that hot. 32:1 is the safe number [​IMG]

    i know this may seem lean, but it's 1 ounce of oil per U.S. Gallon. This is what the sticker says on my gas tank AND I have a manual and that's what it says
