My daughter was out riding 97 GSX yesterday when all of sudden started to bog down. Couldn't get the ski to come up out of the water. She idled it back to shore and when I got home from work it would not start. I'm getting spark, compression, and fuel. I'm just not sure if it is getting enough fuel. It doesn't appear to have overheated. I tried to get a small amount of mixed fuel in the carburators, but still no fire. There is about 160 hours on the craft. Main fuel filter is clean. are there other fuel filters on the carbs?
