Kevin, #26, is the fiber packing that keeps fuel from leaking out of the fitting and the adjustment screw, (#24) as you look into the bowl of the carb where the adjustment goes into the jet, it is made of brass, that is #27, the older carb kits had the option of rejetting to a little bigger to give it a bit more power. Best advice I can give you is to go to the hard ware, find a bit that fits intot he main jet, and buy 4-5 sixes bigger drill bit. drill the main jet to that size, #46 is what I call a metering stem, only drill the bottom 2 holes in the stem, and use the same bit you drilled the main jet. Clean out the shavings, finish rebuilding the carb. You should be able to back the adjustment screw out and make it smoke, or lope from too much fuel, at full throttle, if it does, just turn the adjustment till it smooths out, but still has just a bit of smoke when the throttle is cracked. Another way to check to see if you have the fuel right is to look at the plugs, I like to see a cocoa brown color in the plugs, whitish means not enough fuel, or lean, black meands rich, too much fuel.
