1997 Kawasaki 750 stalls after new plugs and caps??
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 checked compression and both cylinders had about 155psi
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 at a higher rpm?

Welcome aboard, srd1972!
Did you gap the plugs before installing them? That might account for the change.
However, that won't make it run in the water. Most likely, the fuel wasn't treated with stabilizer prior to storage and the (ethanol) fuel went bad and plugged up the fuel system. Most likely, you'll have to flush the fuel system, replace the fuel filter, and overhaul the carbs.
