6 hp Johnson high speed jet
My 6 hp Johnson has developed a problem. No gas above the midrange
throttle setting. I can choke it and get a spurt of power, but nothing without choking. I know the high speed jet is at the bottom of the carb, but is there a way to get to it without pulling the carb? The lower motor housing doesn't leave much room for working down there. Thanks in advance. |

Thanks in advance. Year? It's probably much easier to pull the carb - 2 nuts, the choke link, and the fuel line is all it takes(the cam follower for the throttle stays on the carb). When you have it on the bench, clean it out well(bowl & all orifices, high speed jet), flush the fuel line, pump & screen, adjust the float, and you should be good to go. If you want to try to pull the high speed jet plug/bowl drain and flush the jet out on the engine with the primer bulb, just use a large rag to catch the fuel. Once you loosen the plug a little, it should come out easily by hand. Rob |

But I can't get there from here. I'd have to pull the recoil starter to get at the one on the right.

A couple of pieces of trash flowed out, and now the engine runs like a top. Thanks for the help!! |
