Hello guys, thank you all very much for your insights. bigted and pau13z, thanks for your mention of the transfer ports. I have a small engine book that lists them as "old" and "new" or something to that effect. I guess if you wanted to create a power differential in what is otherwise essentially the same motor, that would be one way of doing so. Also thanks for the info regarding the red spring. I have one kicking around now, and might use it on an engine that is running too quickly.
Regarding the main jet, I've read that they have a different number of "lines" on them, which indicates fuel flow, but I've never come across them. Not that I've noticed anyway. Is that the correct way to identify them?
I could have also sworn one of the float needles I have come across was pink...who knows what it means! I've got some metal ones with rubber tip on order from ebay.
So I guess a Power Torque is a Power Torque. If you swapped over some simple parts you can essentially get "full" power from the things. I'm also guessing that a PT2 does not share a whole lot of common parts with the other PT motors, reading the above post by pau13z.
The only other difference I've noticed is the crank pin.
