Bought a 105 on Ebay a couple months ago. I only went for the 105, but the fella said "on your way out you can have that 12hp engine laying in the stickers over there, it's froze up and I'll junk it anyway". I says OK and threw it on the trailer. Then he says "You can have that 125 frame in the weeds", so we threw that on the trailer too. I tore the engine down( it sure was ugly
) and put some work in it. I had to get it bored .030 over to get the rust out, (but it looks pretty now
). New piston, rings and connecting rod. I had the crank miced and it was fine. The key-way for the PTO side was worn bad
, so I had another key-way cut 180 deg.(wanted about $300 to fix old key-way
). New valves, seats and guides. Head was flat and block is good. New plug, points, points pin and rebuilt the carburetor and fuel bowl shut off. New muffler and made my own exhaust ell (hated to pay that kind of money to buy one
). What i used is a Wagner Steel Bent Elbow, 1" Schedule 40 Pipe, 1" Inside Radius, 90 Degree, 2" Tangents($9.39). I cut 1" off one end and threaded it, then cut 3/4" off the other end (fits great). Cleaned, primed and Painted all parts and the block (not the head). I followed J-Mech's method to time it and I'm going to try to fire it
,tomorrow.
OK, enough chatter, on to the pics (we love pics)
