I just bought a 97 Kawasaki 750 sts jet ski, it ran good (idling) on the trailer. I took to the lake and it would not start in the water.
I noticed the plugs and plug caps did not look good and I checked for spark, one cylinder had a spark and one cylinder had a very weak spark.
I replaced the plugs and plug caps today (good spark both cylinders) and now it idles very low and stalls??
Is it possible when I started it on the trailer previous to replacing the plugs that it was only running on one cylinder?
Any ideas why it idles at low rpm's and tries to stall on the trailer after new plugs and caps??
Do I need to adjust the idle to a higher rpm?
