Tune up complete
Ok...so I completed a tune up. Cleaned the carb, changed oil and gear oil, new battery, and adjusted the valves. Runs a lot better.
Still have one issue. When throttling, when I get between 3000 and 4000 rpm, it sputters, bogs, and backfires. Once I'm over 4000, runs like a charm. What's next? |

Either a vacuum leak or the idle mixture need adjusting. The idle mixture screw is on the left side up on the carburetor. Screw it all the way down and then back it out two and a half turns.
