bought this ski in 2017, posted about it back then. Rebuilt the carb with genuine mikuni kit, replace fuel selector, fuel lines and the ski has been running great the last couple of years, until the end of the season last year. At full throttle the engine would stall randomly. It would start up again without any issues. but randomly stall, almost always at full throttle. I'm guessing a carb issue, but wanted to check here for a particular part on the carb to look at. Screws, fuel filter? any suggestion is appreciated.
