OK, i can help with some of these.
1) i think this is a warning light test button, without the ignition on, press and all warning lamps should light (a couple of mine don't).
2) I think this is the speed control/shut off for the 3pt, I'm sure winston or somebody will explain this better.
3) Not sure where this is, don't even know if mine has it? Can you post a pic.
4) I assumed this is draft control, don't think mine even moves?
5) That is the compression release knob, it should pull towards you, (mine was seized) it should be used when starting for cold (maybe all the time? but i use from cold) it puts less stress on the battery and starter, and lets the oil pressure build before allowing compression. So pull it out, turn the starter, let it spin for a few seconds, then release the knob.
Hope that helps.
Question from me now, does you ignition have the TS marked for turning the key left? When you turn it left, do you get the TS light on the dash? i don't, but not sure if it is the lamp, or the thermo start isn't working.
Thanks.
