First and formost thanks for any help. I am mechanic by trade work for k-dot so i work on everything but jet skis so i have the just idea just no the training he we go with the problem. At full throttle on take off ski is real sluggish but it i pull the choke out to a sertian point and lock it ski pull fast through the take off with my experiance that means ski is getting to much fuel have not checked to see if previous owner adjusted carbs yet as they did drill holes in the seat and air box (i reaplaced it). I do have the seadoo shop manual for this ski any other suggestion on what to look for. Thanks again
