I have a 1984(?) Kawasaki jet ski 440 that I bought late last summer, which wasn't in working order. I just replaced the starter. Now it goes, but it bogs and eventually stales. Seems like it not sucking enough gas. Would it be the Carbs not properly adjusted? Or is the timing out? It runs, but bogs and doesn't want to plane on the water. Please help!!! Thx!
It could be the timing, but start with cleaning your fuel lines, carb, new plugs, get jet specs from someone, and if that doesn't work then rebuild the carb
Sounds like your havien the same issue as me "Kawi" my 89 sounds like a raped ape out of water with a hose hooked up to it but once in water under load it just boggs out. hopefully we get some input
