After carb cleaning atv works like new. There was no visible gunk or contaminants but cleaning with carb cleaner and blowing all jets with compressed air obviously did the trick. Thanks for your help with troubleshooting.

The problem is you can't buy non ethanol here in eu, all gas fuels contain 5% etanol but i used stabilizer over winter when not using it regularly. I'll start from checking the petcock and cleaning the carb.

20241020_164625.mp4 Hi everyone i am coming from Europe and looking forward to join this community. I'm currently riding Kymco mxu300r which is the same bike as Brute Force 300 just different plastics. Recently i came to a problem with this atv when accelerating near full throttle it suddenly lost power like i quickly released throttle but i kept throttle lever in the same spot. Since then it pulls off fine until you are past first 1/4 of throttle and then starts stuttering/misfiring. Same behavior when revving in neutral or riding. Cleaned and gapped spark plug but no better. Could this sudden symptoms be from bad ignition coil and cdi or dirty carb? Carb was never cleaned before but i used stabil in gas when atv was not in use. Atv has 1000 miles carb on it is Keihin cvk32. Sorry for longer post and thank you in advance.
