Hi I have been lurking around since i bought my boat and it came with this motor that did not run (1975 eksa 3hp), I have it running now and it runs well, my questions are is the best place for gaskets boatsportsandtackle.com or is there a better place? I need a manual but they seem pricey...? And lastly for the moment anyway, the carb has a black knob left side that tuns a needle and I dont know if its a low speed or ? And would anyone know the turns out it should be? (The guy I bought this from "rebuilt the carb" and still didnt run... well i went through the carb again and it runs great, but that knob has got me it doesnt seem to affect anything when i adjust it.) Thanks in advance, you guys seem to be a wealth of knowledge about these motors
