Hello just got the ski on the lake and it will not rap out. It is just very boogie. Last year I rebuilt the carbS. Jets are set on 1 turn out on the small jet and 1/2 turn on the big jet. New fuel pump once I replaced the piston closes to handlebars. With a hole burnt in it. The first piston (closes to the rear is cool compared to the other 2. I don't know what it could be. Maybe reeds? Any advice would be appreciated.
