Hey guess what. I've got a fairly well cracked block. I started stripping the oodles and oodles of old nasty paint off the block and saw a familiar beast rear it's ugly head. Lo and behold I had two big'ol cracks on the carb side of the engine. They span almost 2 cylinders lengthwise. I did have the head off (installed new valves and machined in new valve seats(doughnut type)) but I hadn't scraped the old head gasket off yet so I commenced immeadeatly to doing that. My poor lil' tractors injury's grew worse still.
he port side cracks aint nothing compared to the ones on the deck. My God I was looking at the grand canyon when I saw this. If it weren't a sleeve engine the middle two cylinders would be breached. Cracks aren't really a big deal for me though. On some of the 20's cars and truck engines that I've rebuilt and rebabbited I've come across stress cracks and such. This C-123 on my poor lil Farmall 100 has to be the absolute worst case I've ever seen though. :-( How could someone do this to an engine??????? I fixed it though and suprisingly I didn't have to machine down the deck. The cracks are inside of the head studs and the head slips on with no force so it hasn't expanded outward. I left the grand canyon deck side the way it was but I've welded up the port side longitudal cracks. Took my angle grinder and dug into the cracks to trench them out and drilled the end of each one to terminate it. Using my torch I kept the tracks preheated just ahead of my weld. The suckers fixed now but my God what horrible cracks these were? I was so scared that I dusted the old head gasket with chalk to ensure that the combustion chambers would seal against each sleeve (which they did). Has anyone had such a brutalized block????? Who in the hell would run an engine to where it would burst like this?????? I'm thinking I'll put aside a little green to purchase a spare block to keep handy should anything ill happen to this one. How much do C-123 blocks usually run?????

Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
