I have a bone stock 2008 RXTX - ran fine for a few seasons nothing major on it other than just spark plugs and oil every season .
Took it out for the first time this season it tends to stall after start unless I apply a little throttle - creates a lot of dark gray smoke at 20 to 30% throttle As I’m just moving about the water at 20 miles an hourand then runs like a champ once I exceed 50% throttle. No smoke at that level I don’t think but hard to tell obviously. The throttle effect on the acceleration is kind of jerky… Ski goes from ‘slowly getting about’ smoking to hell to ‘I have to let go of the throttle’ as it accelerates quite faster than I am asking it to. I thought just need to clean the throttle body - maybe the butterfly is dirty and sticky - But I thought I would ask maybe someone here recognizes the symptoms as something obvious.
The ski has 200 hours I have owned it since 110. Charger serviced at 100 hrs.
Only oil changes since then (5 years).
-
Gas was last year ‘ s but now on second fresh tank of 93 octane.
Double the fuel consumption of my rxt. On the last tank.
Photos of plugs I took out. Plugs were new last year and only used for 5 hours. I left them in at first (this season) but now replaced. - no change in behaviour
What may be causing this very rich environment? Top plug is rear cyl.
Thx in advance for any advice!
