[FONT="]Yamaha 150TXRB 2-stroke carbed starts and idles fine, but bogs down going through a range of about 1500-2200. It doesn't like sitting at that range at all if trying to troll. Push through it and the engine runs cleanly with zero issues all the way up to 5000 rpm. From idle doing a fast hole shot there aren't any issues, but barely can sense that hesitation going through that range. Fresh gas. Could this be something in one of the carbs? Timing? [/FONT]
