I had the misfortune of losing the back half of my muffler yesterday on my maiden flight of my somethin' extra. It has a TT .46 pro engine. I aquired an OS muffler, and after a very minor adjustment to make it fit, it is on securely. The OS muffler is physically shorter, and smaller in diameter. I also removed the baffle.

Will the new OS muffler, due to its smaller size, not let my engine run to full throttle? Do I need to readjust the carb? Still learning the tuning of engines, so if so, I will have to get some help tomorrow at the field.

Thanks,
