Hello all. I have used this forum for years from time to time and always found what I was looking for. Today I finally joined as I ran into an issue with the kids’ Sportsman 90 that I couldn’t find anything on.

We bought this machine used about 1.5 years ago and has run good up to this point. The machine has been run several times this year and this time we had it out for a week long trip. It was running fine and then quit moving. It will idle all day long but as soon as you push the throttle, it sounds like it is on the rev limiter. However, when you engage the brake, all is well. The motor will wrap up normally. Let off the brake and try to go, and you are back to the rev limiter.

I pulled the carb and checked the jets and all is well as expected. I suspect this is some "safety" measure shorted out or something but am looking for some help.
