Tim, take a careful look around the side if your thermo, it likely has an arrow stamped on the side for the direction of flow. The direction of flow is from the engine - into the radiator. There are a couple different styles of thermos, but in all cases, the "working end" of the thermostat, which is the end with the temperature sensitive wax plug or bimetallic disc, is the end that faces towards the engine.... but look for the arrow, that is the easiest way to be sure.
You don't need any sealer on the thermo, just stick it in the hose, it won't go anywhere.
I thought I saw a a schematic of a MS carb on here a couple weeks back, maybe look through the archives. Assuming you have a manual, use that, it has a lot of good info, and good pics that are lacking in the lame instructions that comes with the rebuild kit. Everyone had an opinion, my opinion is to not use sealer on any of the carb gaskets, especially silicone gasket-maker type stuff. The gaskets are intended to go on dry. Silicone can ooze out into the carb and cause future problems. If you must use sealer of some sort, use the thin stuff like Hi-Tack, or similar, not silicone. Keep in mind anything you glue-up with sealer will just make your "next" rebuild more difficult cleaning all that stuff off. One last tip on the float level adjustment, clamp your carb in a vise so it is level, use a fine graduated measuring device to set the float gap, not a big clumsy tape measure. Set the gap about 2/3 way down the side of the float towards the free end, not up by the needle valve. George
