First of all nice site!! I have a '96 Johnson 35 hp J35QLEDC. A couple of years ago I removed the vro on the motor so I don't know if that has anything to do with this problem or not. The motor will run pretty good on the trailer and even times going up river at wot. Then sometimes it will either just lose power like you unhooked the fuel line. When running good it will do about 30 mph loaded. Then I can feel it lose a cylinder or something and it goes down 2-3 mph but continues to run. Also it will be hard to start sometimes after we sit and fish for a couple of hours. After it finally cranks, it will not be running smooth for a while like one cylinder is not firing, then all of a sudden you hear it clear up and it runs smooth. I have rebuilt all 3 carbs and changed the power pack and coil. Yesterday pulled all 3 plugs separately and they are firing. Ordered new fuel filter but was not clogged. Replacing all fuel lines today. Also noticed a little gas/oil below one of the fuel pumps so I ordered the large o-ring that goes in the pumps. Sorry for the long post. Thanks in advance!!
