Ok so I bought this sled last year and put 1000 miles on it, this year I’ve put a tank of gas through it and one morning it just didn’t start. It flooded itself out like crazy (it’s efi) and I tried changing plugs but they looked fine. I just replaced the reeds and checked the throttle servo and the fuel pump is working good. On the rare occasion it does start it runs either 2900 rpm or 1500, and it bogs out and dies at 3900. I’m out of ideas on what it could be. Any help or ideas would be greatly appreciated.
