I had purchased "SBT carb rebuild kits", assuming any kit was as good as any other....WRONG! Ski would not throttle up on the water (ran fine on the trailer). Replaced SBT kits with Mikuni OEM kits.....blast off...ski was back to normal...better than normal actually, has never run better.
what kind of problems were you having by not using genuine makuni carb rebuild kits?
i have just rebuilt mine in both my skis. i have a 1999 and a 1998 gtx limiteds and love them. just did a rebuild on one of the engines and almost done with break in. i changed my arrestors to after market and changed jets
