im not shour but it could be air bubles in the fuel line ..or the lowspeed needel could have vibraited out a bit...i had the lowspeed needle come loos on my raptor once and the engine started making a high rpm screeming sound,,hope i hellpt:)

thanks for that there seems to be quite a bit of fuel dripping from the muffler and when the heli is ideling theres fuel spitting out the top of the carb

the high speed needel is to rich then so u might want to leen it off a bit but be cearful that u dont leen it out to mutch or your engine will overheat and break down after a while...try to keep it jst a little bit rich tho your engine will last mutch longer;)

Clutch slipping.

I'd check thte clutch first. If there is fuel coming out of the carb, it's not likely too lean and too rich will not cause a high revving engine.
