I've been doing a little work on my '57 Johnson 18 horse the last couple days, and I got to thinking (I know, bad thing). How in the world does this motor get air to the carb? The hood is so well sealed up, with a gasket at the bottom, gasket for the face plate, and a plate where the pull cord comes out. Seems to me that the motor would starve for air.I know I can answer my question by taking the hood off next time I go out, see if RPM's go up, but I was curious if some of the more experienced ones here can tell me about this. Did they take the hoods off for racing? Make an air inlet? Didn't bother? Do tell. 55 "always after more speed" Crestliner.
