<x-charset iso-8859-1>Something to keep in mind, Robb, is that #2 is not at the top when you are
setting #1 at TDC. In fact, it is somewhere near the bottom, so when you
rotate the crank counter-clockwise, you are actually bringing #2 back up.
Remember the crank is staggered and looks something like this:
[3] ==
== [1]
[4] ==
== [2]
...and when the piston comes to TDC, there is actually a point where the
piston does really not move up or down while the rod is moving to the
opposite side of the crank, because the connecting rod is virtually moving
laterally while the rod crosses to the opposite side of the engine case (if
that makes any sense). This is why when you put something in the cylinder
(like a wooden dowel) to "wait for the cylinder to come to TDC" you will
find that although the dowel has risen to the top (and the cylinder APPEARS
to be at TDC), what you are actually experiencing is lateral movement of the
rod across the crank while the TDC notch lines up with the case.
Good luck!
