Hi - okay, i've fixed mine (sort of)...
Also spoke to a ski mechanic who told me how else i could have done it!! ha ha !
1. My carby didn't appear to be working, so i stripped it down and rebuilt - discovered there was a problem with low idol screw... Ended up contacting a jet ski mechanic who has worked on heaps of these and recommended replacing it with a marine carby built for a different 2 stroke 700 engine (sorry, i can't remember what one!)...
Replaced the carby - would only start and run with starter fluid...
2. Discovered that the problem was in the fuel line, despite flushing the fuel tank, still had the same problem - a different mechanic (small engine mechanic) said that sometimes the fuel pumps (suction) don't do the trick and you need to supplement the flow with either some sort of pressure to the fuel tank or an elect fuel pump...
Installed the pump and she ran like a treat!! (still won't start without starter fluid - but once started will run all day

)
Well i THINK it will run all day!!! Within an hour of having it back in the water i heard a terribly noise (thought it was lower end of the engine) but turns out that my bearings on the impeller shaft were completely rusted and corroded! they gave out and i'm now getting parts i need to fix the jet unit!) (apparently the bearings need to be changed every 40 or 50 hours - my ski has less hours than this, but eventually found out that it was used in salt water then sat for about 2 years and never used - hence my problem)...
Hoping when my jet unit is fixed it will be trouble free for a little while! I intend to put it on the market as soon as it's going and just use it until i sell it!!!
Think i'll wait until i can afford a new one without all of these maintenance problems
