Hate to say. its still running rough after all that. One thing i noticed it runs better with muffs than in water. Back pressure problem? I did change reed valves a while back. It was spitting gas out the carb. other than that i am lost. I have had this boat and motor 21 years with little maintenance. The lake i live on has a lot of stumps and i have hit my fair share. I am noticing a little rattling noise. But my compression is good 120 both cyl it runs good at mid high rpms. i have the static timing at 30.
