Hey nick. The only true way to clean the carbs is to get them off and take them apart. There are small internal filters in there that will clog up from time to time. I would do a whole fuel system cleaning. Start with the lines, if they are the gray ones replace them with black fuel kine hose form an auto parts place. From there clean out the big inline filter and also take apart the fuel selector switch and clean it out real good.

My carb bolts where hard to get off the first time as well. Just be pateince and thorough and don't strip anything out, try some penetrating lube to loosen them up.

yes iv got a same issue

iv got an sp 96,spray the carb without uninstalling and when i have a ride, had a problem on full throttle ,then i take carb a part, cleaned and rebuilt it and its worst now,when i trying full throttle, its like you start the jet ski engine and leave it to run without holding the accelerator
and another question ,can i use 95 or 97 octane petrol for my jetski ?
