That sled should fire all three coils at the same time (3 times per revolution), so it shouldn't matter if you mix then up even if you could. You can use propane, starting fluid, or carb cleaner to test for air leaks. Just be careful with flammable stuff, and stuff that will eat plastics. Did you reconnect the TORS leads to themselves after disconnecting? As stated above, are you sure which screw you turned? Which way did you turn it? Check all of the cables to be sure that the cable housing is seated properly on both ends and at the junctions. Wiggle the wiring, cables, and anything that is loose, to see if it changes anything while running. If you still can't find it, I would get your electric tester out, or find someone to help you if you are not familiar with electrics.
