I've been researching and working on this problem for a while. Engine starts and idles just great up to about 2500 RPM and unless I choke it or pump the throttle, the engine will die. When I get above ~4500 RPM it runs great up to my max rpm of 7000.
What I have done:
New hoses, and selector valve.
Had carbs professionally rebuilt. (2x)
Installed a set of carbs from my other 787 on to this ski and had the same issue. Carbs from this ski moved to other jet ski and they work with no issue.
Carbs linkage has been synced' visually.
Cleaned and inspected rave valves. Now set flush with top of dome. The work freely. (they are the original rave valves. Non slotted)
Installed fresh voltage regulator.
New spark plugs.
Compression in the 130's as best as I remember when I checked it last year. (a little low but not so much I should be having this bad of an issue)
None of this seems to make any difference in solving my mid range issue.
I bought this jet ski with these issues thinking I could solve the problem.
I have not messed with the water regulator. That is next if no one else has any suggestions as to what I should try next.
