Tecumseh Motor

Hello all, as you can see I am new here I have a Tecumseh motor, and a LOT of questions. To begin with I bought a Wheel Horse tractor model 656. This tractor was produced in 1966 with a 6HP Tecumseh 6 HP motor. When I got the tractor, the motor was stuck. I put a pipe wrench on the PTO pulleys, and it freed up pretty easily. I decided to tear it down and do a complete rebuild on the motor. (BTW This is the first time I have ever tried to rebuild a single cylinder 4 stroke motor. I have done small block Chevys, and lots of 2 cycle Lawnboy motors.) What motor is it you ask. THAT'S my main question. The tag riveted to the shroud says, HH60-10513A. That is not a good spec number I have been told, more than once. I have a pic of the tag, but I cannot upload it. Maybe because I am not doing it right, or because I am a new member.. I HAVE LOTS OF PICS! I disassembled the motor, to my dismay I discovered a crack in the block, and the sump cover. It's as if water were allowed to accumulate and freeze, and broke everything. Before I go on a parts ordering spree, I check a few things out. The piston measures 2.750 in diameter, as does the bore. The rod journal on the crank measures 1.187. All of this indicates a 7HP motor according to the information I have found.

 
According to the information in this handbook, my motor measures to be a 7 HP. Also according to this handbook, HH designates Cast Iron block. Mine is aluminum. I am beginning to believe this is not the original shroud to this motor. I have lots of facts and pics, but I can't seem to post pics. Maybe if I submit this post, and a couple mre, I will be allowed to post pics. I'll be back, with more info.  Thanks  Greg

    Well, apparently it won't let me insert a link either. I am here to give more info, mostly just to make another post. I have casting numbers from the block, crank, and carb. I don't know if any of that is useful or not. My local small engine guy orders me a lot of parts, and has helped me in the past on other projects. The Tecumseh rep also told him, that it was not a good number. He was holding the shroud in his hands. The number is clearly visible. Nope   Still won't let put in a pic. How many posts does it take?

    It should allow to post an link. But them is a little different than many forums. Just add the weblink address on a separate line. like this:
     
    http://forums.jackssmallengines.com/Message/12846-Tecumseh-Motor/
     
    As images they should be Jpeg or PNG to be accepted from an image hosting site as far as I know. I do know BMP (bitmap) are not accepted. Also be carefully of sizing limits try not to post over 600 dpi x 600 dpi images.
