what body the trottle body? and that pin on the very end of th spring?
The body he is talking about is the carb body, where the slide goes into. If you look down in that, you will see a little pin sticking out from the side, the size of pencil lead. Then look at your slide, the part attached to the cap, the spring and the long needle, that will have a groove in it the entire length of the slide. Those two need to line up, and the slide will easily slide all the way down to the bottom. Your needle (or valve needle) that is attached to the slide, should easily go right down into the needle valve, which is what your main jet screws into. I forget, do you still have your TORS?
As for the pics, I'm no good at photoshopping things..plus I'm at work and don't have access to my photos. If you look at the pic though, you'll see a big hex (rotate phone or pic so that is on the right), then just next to that you will see a smaller hex and then the next will be the black hole...that is reading the pic from right to left. The larger hex to the right, that is my needle and seat...the seat is the hex and the needle is the little part that falls out of it that should have the rubber tip. The smaller hex is my main jet, if you zoom in you will see the one in the picture is stamped with a square in a square (tough to see) and then 150...that is a #150 main jet...DO NOT PAY ATTENTION TO THAT SIZE, MY CARB CAME OFF A STREET BIKE WITH 4 CARBS AND CYLINDERS. Then, in that black hole, is my pilot jet. If you inspect all of these parts, you will see a stamping on them, that is their sizes. When you go to put these parts back in, you can't confuse where they go, they only fit in their rightful location. Also, just thread them in until they are seated, then lightly snug them...1/16 of a turn of the tool, just to keep them from loosening from vibration. They don't need to be cranked down...you don't want to strip the threads.
Like Blaaster said, there is no sealant for any of these parts. There will be a gasket though, between the float bowl and the carb body. 99 times out of 100 you can reuse that gasket, unless you see it is ripped or you used a screw drive to pry the bowl off the body.
As for the lines, the only one that needs to be hooked back up is the petcock for fuel supply...unless you have your oil injection hooked up. If not, that should be blocked off. The two other lines are just vent lines, you can actually keep them hooked up to the carb next time.
