I am at that point in reassembly of my 150 hp Franklin that the carb is next. I have the 2 venturi MA3SP Marvel-Shebler and it has some AD's; one calls for checking to find loose venturis. Does anyone have advice re assembly kits, say gaskets, floats, needle valves? It has never caused any trouble and it passes AI inspection but it is off and available to be worked on.
