MXU / MXU 150 Dies When I put Into Forward or Reverse
« on: May 31, 2022, 04:53:31 PM »
I recently purchased a few used ATV's for the fam. Kymco 50 mongoose, MXU 150, and a Honda 300ex. I don't know the exact age of the MXU 150, but I'm assuming it's 2007 give or take. Anyway, the 150 was running fine for a few days, but overnight it now dies when I put it into forward or reverse. I've tried a hand full of things which would result in a day or two or even less of things appearing to be fixed, but the issue eventually comes back up.
Things I've already tried
- Cleaned out the carb (didn't even need to be cleaned, but cleaned anyway)
- Changed the fuel and air filters (definitely needed to be changed)
- Adjusted the idle, which worked pretty well when I found a sweet spot. Adjusting the idle seemed to have the best results, but now even adjusting the idle does not work.
- Checked the safety switch on the left brake handle and it appears to work fine
I'm not very mechanical so any suggestions would be appreciated. Most of the things I tried were suggested by friends and this I read online. I've talked to some ATV owners that I know and they can't figure out what's going on. It's a really old Kymco 150 so, I dont' want to spend a lot of money taking it to get repaired if I don't have to.
