So I took the ski out today(1993 SeaDoo Sp) and it stars up fine idles fine runs until you give it full throttle then let out. Once you try to give it more throttle it Boggs down then dies. After you start it again it has issues re throttling. Like it doesn’t want to run . Any help?

When was the last time the carb was rebuilt?

I would definitely rebuild the carb if its a used (new to you) ski. Bogging is a carb issue most of the time. ONLY use Genuine Mikuni rebuild kits with needle and seat. I can not stress it enough, I speak from personal experience. If you use knockoff kits such as winderosa then you will just have the same problem. They generally cost $25 more per kit and are a little harder to find but I usually get mine from Bay Area power sports. They're around $75. If you have dual carbs you will need 2 kits. I assume you probably have a single SBN 38 but don't take my word for it. Hope this helps
