im new to rc and i bought a used ttr and it ran great for 2 weeks with only minor tune ups and carb tunes. then i was running it and came out of a turn and it made a continuous high pitched noise until i stopped the engine (621 P) and nothing looked out of place and it wasnt overheating or even hot for that matter. So i put it on the starter box and it started but did the same thing within 5 seconds. if anyone has any advice let me kno. the carb was not wide open which was y i was confused that it made that noise
