Hi all,
Update on my 140 losing power. Yep, new points, condenser and coil helped alot, but didn't quite get it done. So, after 5 hours of chisel, torch, hammer, pipe wrench, air hammer, yanking, sawzall (3 blades and a 1/8th inch gouge), soaking and all trying to get the muffler to release from the exhaust up pipe, I had an epiphany. Take the exhaust manifold off and remove the hood and muffler together.
Okay, so I can finally get at the engine. There has been an oil leak from somewhere up high and forward for a looonnnggg time, and there appears to be about 25 years oil grease dirt build up all up and around the front. I spent several hours just getting the 2 to 3 inches of crud build up off of the areas I wanted to work. The crank flywheel, the belt, even the fan were all riding on this crud and had about zero clearance. I'm surprised the engine would even turn over under battery power.
So the valve cover finally comes off, and there appear to be two bent push rods. (standing on the right side of the tractor in the offset) The 2nd rod on #4, and the 1st rod on #1 are both canted inward / bent, and riding on the head casting. Oh joy. In addition, I find out where the leak has been. Whoever put the valve cover on 25 years ago, managed to let the right front corner of the gasket completely miss the corner of the cover. Of course it has shrunk and it mica brittle, so I can't salvage that. And to add to the days festivities, I managed to poke a tiny hole in one of the radiator tubes, so i drained it and had to take off the radiator. I think I can patch the hole if I snip away a little bit of the fins surrounding, but I have no idea what kind of solder is proper!! Tin? Lead Acid core?? Anybody know??
Anyway, I'm going to put in two new push rods, adjust them and all, 2 new gaskets for the valve cover and the exhaust manifold, and one quart of Marvel Mystery Oil to help with the potentially sticky valves. Patch the radiator (hopefully) and my lost power issue should be history. By the way, 62 psi on #1, about 67 on #'s 2 and 3, and 60 on #4 cylinders. What is the right compression for the 140 four banger gas model?? Thanks to all that have helped and kept me going on this. Looks like I get to paint the engine a little sooner than I expected.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see.
