   Well I finally got around to taking the head off of my Granpas old 44-6. It has been in an old barn for the past 35+ yrs and it hasn't ran at all during that time. It was just parked and left there for some unknown mechanical reason. The crankshaft and pistons move, but the camshaft doesnt. The small half moon key that goes on front the camshaft, that the gear goes on, isnt there, so that could be why it doesnt turn, but that key had to have sheared off or something for some reason, that is why I think the valves are stuck. Someone tried to pull start it many years ago, and the pistons were free, and the valves werent. I dont know if the valve or piston rods are bent, but chances are they are. Also, while the tractor was sitting all those years, the starter was off, so mice or who knows what else couldve gotten in there. If you look at the pics, you might be able to see all of the crud, dirt, oil, and who knows what else is all on top of the pistons. You can also see that the valves are burnt. So what do you guys think? I believe it needs a full engine overhaul, or maybe a differnt engine. I have another engine that I could swap with one that is in the tractor. I know it is a crysler flathead six cylender that my great grandpa took out of a tractor that they wrecked. One of the spark plugs were take out of it though, so there is dust and dirt in one of the cylinders that would have to be cleaned out. I dont know what it looks like on the inside, but I do know that it is loose and the distributer will turn, which means that the valves arent stuck or anything. The one that is in the tractor is a continental flathead 44-6. I know that the crysler had a little more power, so when I want to take this tractor to the occasional tractor pull, it would be a better engine. What do you guys think? I would really like to hear all of your thoughts on this one. Sorry for the long post.
