I have owned this ski for the past several years. Every summer it either gives me a fantastic day at the lake or a headache.
Ran the ski for about 1/2 hour through wakes at about 2 thirds throttle. When I reached a protected area where the lake was fairly flat I ran at about 1/3 throttle. I heard steady popping, directly timed with the engine speed. If I didn't know better, I'd say it was normal. As I increased the throttle, I could notice when the WOT circuit kicked in, the popping when away and the engine hummed nicely. As I pulled into a cove and came to an idle, the ski ran about 30 sec and it died. Started it up and ran about 15 sec and it died. It progressively got worse until it was almost impossible to start. I pulled over (pulled the plugs, they looked dry/tan) and decided to leaned the mixture screws an 1/8 at a time until it ran better at idle and it did not die, however I lost full throttle, and the popping really never went away either. So I enriched the mixture once again to where it was before.
On the way back to the marina it initially would only run about 1/2 throttle. I popped the fuel filler cap, no change. Eventually it revved beyond full throttle and I kept it there until I got back to the marina. Between the no wake area and the docks, it consistently stalled.
I have rebuild (OEM parts) the carbs 2 weeks ago, set the pop off valve to spec, replaced the the fuel hoses, fuel selector switch last year. I am running premix at about 40:1 or 2.5oz per gal. Compression check today 175 each hole.
Would my coils give me similar symptoms if they were braking down? Although typically something like that would break down under load, she runs great under load. Any suggestions would be greatly appreciated.
