HI All. i am looking for some answers or help with a quantum 4.5, it had been sitting for around 4yrs , i have taken the carby off and found it dry an a build up of like calcium white powdery scale in the carby almost electrolysis like (if you own a boat) ok so i have run a wire through Evey hole , removed seat and replaced it , removed the air/fuel screw and cleaned ,same with the tank. it starts easy but struggles to get off the idle, tried the air/fuel while running but no good , but if i cover half the carby intake it runs normal , indicating a possible air leak so that was checked and tested and ruled out, i have checked (visually) the valves but not the seating? any help on this would be gold
Mark
