As noted in other posts on this site, I've been have problems with the motor stalling when trying to go to WOT. Have previously replaced fuel lines and primer bulb. The prior owner has rebuilt the carbs a couple of times, most recently in July when we first experienced the problem. I ran the motor in the driveway yesterday and removed the plug wire from the plugs one by one. I noticed little if any change in running when I removed wires on the starboard side. I did notice a drop in performance when i disconnect the bottom plug on the port side, although I didn't notice much change when I removed the middle and top plug. Any thoughts.
