While trolling the other day on our pontoon (motor was and has been running great) it just died in the water. I checked and both cylinders had good spark. I pulled the boat out of the water and took the carb off ( gas came out of carb when I removed)and blew jets out. Put the carb back on and the boat fired right up. Put it back in the water and went for a ride. Trolled for about a mile before it got cold outside and decided to go back home. I gave it full throttle and it ran great at first and then sputtered a couple of times before we got home. The next day I drained all the gas from the tank and ran it thru a filter before cleaning the tank and refilling. The boat started right up and I let it idle for about 5 minutes before it stalled and now it wont fire again. Do you think the hose from the tank to the motor might be contaminating the carb? Also is there something I can do to clear the carb again without having to take it off? I will have to pull the boat out of the water again to take off carb which requires removing the starter to get to. Kinf of a pain in the behind. Any help is appreciated. Thanks.

Ethanol has wreaked havoc with non alcohol resistant lines the last few years. Replace all of the with new resistant is about all you can do. Sorry, there is no way to properly clean a carb without taking it off. Put a small inline fuel filter on between the primer bulb and your engine.

You might get a fresh tank of fuel and line, hook up to the mtr, remove the carb bowl drain and pump the primer bulb to maybe flush any crap out of the carb.

I second firemans response, replace ALL fuel lines, remove and re clean the carb blowing out all jets and orifices. Before installing the carb again flush line into a container from the pump to the carb and check for clean fuel. Tiny black pieces of rubber from old lines can reek havoc on a carb. Oh and fuel is supposed to come out the carb upon removal.

Thanks for all of your replies everyone. I will replace all of the fuel lines and take off again and clean the carb before putting back in the water. Hopefully this will take care of it!:)
