Okay, i just received the 31380c Tecumseh rod, rotary brand piston and ring set.  in the ring set, the instructions stated how the rings were to be installed on the piston so i did that.  easy enough.  next is testing the fit of the piston in the bore.  the instructions for the rings said that the ends may have to be filed to get the right clearance or fit in the bore.  so that's something to look into.  the 31380c rod was the last rod my local supplier had.  shen she tried to get another tecumseh rod from her supplier, they couldn't get one.  so it looks like maybe the 31380c rod may be going the way of the dinosaur.
Tomorrow, im going to draw up the rod then try and get the engine put back together this weekend (new oil seals, plenty of assembly lube, and i need to grind the new lifters for the right clearance)
ill take a few photos of the parts as well as the build and host them on my website.  ill post the links here so you all can see the progress.  also, i have the following files in PDF format.  for those who want them, send me a message and ill send you the links where you can download them.
