After I over hauled my 200, motor, had fuel pump and injectors done. It always had a weird sound. Went through and reset valves. It ran ok but always had the feeling something wasn't right. This spring the return line from the injectors was leaking, about a foot from the fuel tank. The line was spliced with a quick slip type connector. I ran a new line from the motor to the tank and now the motor sounds more like a 301 should. All those years it must have leaked enough to let air in until it started leaking more fuel out.
