02 GTI LE Acceleration Problem

[USC Justice]

One other thought as I have been puzzling over all this. What type of fuel filter should be in-line on the fuel line? All the fuel lines were the newer black automotive fuel lines and there was an in-line filter going to the lower connection on the carb. Additionally would a clog in the pulse line (going to the engine block) also assist in creting this frustrating condition?

From the factory none of my seadoos had an inline filter other than the standard filter. However I do have inline filters on my seadoos, I forget the part number but they are made by Fram and have 1/4" inlet and outlets.

A plugged pulse line can cause problems, but in my mind not these problems, with this set of symptoms. However, I have learned in my old age to begin taking my father's advice. He would say "it costs nothing to check".

New update. Had a chance to spend some time at the lake today. Here is what I have done today. Pulled the carb that goes to the 99 GS off and put it back on the proper ski. Triple checked the high and low speed screw settings on the new carb, and re-installed it on the 02 GTI LE. Also put another temp sensor on the 02, as some have suggested that there is a chance this could be the culprit. I also changed the fuel line from the Sea Doo Fuel filter (even though it looked great), and the in line fuel filter after that. I also changed out the pulse line. Is it odd that it is on the mag side? On my other skis it is on the PTO side.

All of this to say there was NO NET CHANGE. The ski behaved exactly the same as it had before. It still delays when you grab a handful of throttle. That delay does get worse the longer you ride.

This leaves me still puzzled and wondering a few things:

1. Could the rotary valve be off a degree or two and thus causing the problem?
2. I have heard of the clearance being off on the rotary valve causing bogging problems, could this be reasonable?
3. What tools will the Dealership use to try and diagnose this? Do the plug in diagnostic tools provide a great deal of information?
4. Could the engine being misaligned cause any of this? I thoroughly don't believe that this is even possible, but I find myself doubting everything that I have done thus far now.

Also had the fun realization that the front left motor mount was broken. Not as terrible to swap out with the ski in place as I thought.

One other thought, out of the water (on or off of a hose) it will rev immediately and without any hesitation whatsoever.

Ok, I suppose that's about everything. Anything else I should consider before going to the dealership? Planning to just ride it as is next weekend for Labor day, and then drop it off after that and ask them to sort it out. It is so close to being right that it is making me crazy.

Thanks in advance.

Not so much to bring a thread back from the dead, but to share the (hopefully) final resolution. Gave up and took the ski to the dealer the week after labor day. They called yesterday to say it was finished. The rotary valve housing was chewed up and there was a gouge in the rotary valve as well. replaced those and new o-ring and they say everything seems to be perfect on the hose. Since it is supposed to be 80 degrees here on Sunday, I'm going to go out for a lake test. Can't say I have ever been able to ride in December up here.
