My restored 53 sunliner always has an exhaust smell that is heavy like it is running too rich. Runs great, however. Also notice that very little choke is needed once it starts cold. Wondering if the main jets could be incorrect? Float level is down about as low as it can go and still not suck air. Any carb experts our there? Thanks, John Wells

Close the idle screws all the way[gently] with the engine running. If it doesn't die, it is probably the power valve.

many carb leaks are hard to see as the gasoline will make its way out of even a pinhole in the carb casting, or a leaky gasket. Over tightening the assembly screws can warp the diecast easily. The first thing many do with a slight leak is to cinch down the screws, only to see the leak worsen. On old carbs we check for warped gasket surfaces by placing a sheet of fine emery paper on a piece of glass, then rub to gasket surface across the paper. It will show even the smallest warped places.

Bob, When I was young, that piece of glass "trick" was pounded in to my little brain when being taught how to properly rebuild these old carburetors. It is rare for me to find one that does not require "truing".
