Spark plug fouling
Ok, I'm starting to get better aquainted with my 1996 SLTX. Overall, it runs very well with some days being better than others. I'm starting to think the difference in how well it runs may be a fouling spark plug.
If I let the ski idle too long, say for a minute it usually will stall and its getting harder to restart. Yesterday we were riding all day and one time after I got it started, it was only hitting on 2 cylinders until the third plug cleared up. It was smoking like crazy. Then I got full power back and away I went.
So my buddy Mike is saying I need to lean that cylinder progressively until the plug stays clean and he said another plug appeared to be lean.
Any feedback would be greatly appreciated!

What spark plug are you using? If it's the right one, then I would start looking at the carbs for resolution.

Definetly make sure you have the correct plugs,try some new plugs.As far as diagnosing,I'd start with a compression test.

I'll pull a plug and make sure they are the right ones...The previous owner took good care of the ski and I remember seeing receipts for the correct plugs.
The carbs are spotless looking down the throats but that might not mean too much. I don't think they've been rebuilt and the ski have 140 hours on it now.

hmm ok. because i dont see the carb settings for a 1996. i belive there is only a low speed screw that is adjustable on each carburetor. that screw should be set to 1 screw out from lightly seated position.
the 1 screw out from a lightly seated position is for a 1997 sltx model
