Hello im new here. I have a Waveblaster II 760cc with dubbel sbn 44. The watercraft is stock and i have done a rebuilt of the whole machine. with new gasket in the whole engine and carbs. But i can't get the watercraft run good. I have test a lot of settings on the carbs.
The machine is very hard to start but not if I run it and stop and start again. I have a good brown color at the spark plugs. How can i fix this?

Sorry for my bad english // Erik.
