After not riding this PWC for 3 years had the old fuel and synthetic oil flushed and started. Basically this seadoo is brand new, but it will not run good since sitting. I flushed the fuel lines yesterday, and now top end is 45 max, still a little sputtering. I used carb and choke cleaner on the carbs to try to see if teat was the issue as well. The sputter continues, the top end is now 45 versus 65-70. The only fuel line I did not pull is the one from the shutoff valve to the carbs. Very little build up in the lines if any. Like I said this PWC is basically new. Since I was pulling lines, I pulled the tank baffle valve from the gas tank to clean the screen on the bottom.. not much there either... This is a pain in the east side of a donkey headed west...
