Re: Just bought a1985 honda 7.5 horse
I have a used 8 HP Honda BF8A, from about 1993 or so. I did replace the impeller, fuel pump diaphragm, fuel hoses and fuel filter after my first season with it. I also found that the pilot (low speed) jet tended to clog by the end f the season; cleaning it (and the whole carb) carefully helped a lot - it used to be hard to start and keep running when put in gear, and so far (in a tank of water) it has been fine. I don't know how similar the 7.5 carb is, but you may want to look at that.
