After fixing my starter problem, I'm now having problems with the carb on my Bayou. I pulled it off while working on the starter to put in a new float needle to cure a fuel shutoff problem. While I had it apart, I cleaned it thoroughly, checked the jets, checked/ cleaned/reinstalled at original settings all adjustment needles. The problem I have now is the *#@?!! thing backfires out the exhaust at about mid throttle and won't go faster than that. I've tried re-adjusting the float level up slightly, tried adjusting the mixture needle up and down, pulled it apart 3 more times to clean it even more, but it still backfires. It idles great and has good power up to about half throttle but sucks after that. Fuel flow is OK. It doesn't have any vacuum leaks. The original float level setting was way off(high) when I first took it apart, so I set it by the book when I put the new float needle. What am I missing???
