Trying to bring this ski back from the dead. Completed a minor restoration and replaced a lot to new.
Took the ski out the other night for the first time, and the throttle won't transition past 1/3rd throttle in the water. About 20mph or 3,500 RPM's. Brought it back to the trailer. Runs normal with no load with the hose on the trailer.
Spark plugs are soaked, and looks and sounds like it's running super rich. These were new plugs installed since the first run on the trailer on the hose this year.
I pulled the carbs back off and went through them to see if I missed something. Checked everything per book. Most I found was the high speed needle on the pto was set at 3/4 turn out instead of 1/2 turn. The pop off's were in the range of 32-35. I had one needle not able to hold 10 psi for 30 seconds. I'll change that out. Arms heights were correct.
I'll reverify the fuel pump check valves. Diaphram test was good. What else would cause a stupid rich condition?
It was suggested to me that the new voltage regulator i got from OSD might be limiting throttle. I was suggested i try unplugging the red, which is the charge output, just to try and see if the rpms go up.
Also snipping the ends of the spark plug leads and screwing the caps back on. I can do that.
I did verify the water pressure regulator setting, and the rav valves were removed, cleaned, and reinstalled.
Anything else I should be looking at? I thought it was a carb issue, but now i'm not so sure.
