i have a late 80’s 260b with a qjet on it and am having trouble with a bog under heavy load. If I have 4 people in the boat and go to wot the engine will just bog, if I go to 3/4 throttle it will put fine up on plane. If I am pulling a tube or put on my higher pitch prop I can only go 2/3 throttle before the bog. Took the qjet apart and cleaned it and installed new gaskets ( have full rebuild kit ). Secondary air plates seem good and have good spring tension to keep closed( known problem). Secondary Air plate vacuum diaphragm does not leak or bind. Noticed the qjet does not have the four tubes in the air horn, only two( missing the well- feed tubes and holes in air horn) but from a little searching it seems that is correct? To me all seems to look good with the carb but I have not watched it operate under load. Thoughts? Advise? Anything is appreciated. Thanks
