This afternoon, I made a new set of plug wires and put them on, then I put the gas tank on and about a gallon of gas in it. Hit the starter but it wouldn't fire. I check for fire at the plugs and that was good. So I pulled the plugs out and started checking the compression. #1 had 40#'s, #2 had 30#'s #3 had 40#'s and then the battery ran low, so I quit. Looked inside the cylinders with Bore scope. Cylinder walls are shiney where the pistons ride but full of crud above there. I took a long screwdriver with a hook on the end and reached in and could feel a ridge at the top of the cylinder wall on #1 cylinder. I didn't feel that on the others I tried . I have a spark plug with an air fitting welded into it, tomorrow I'll put it in and hook up the air hose and see where the air comes out. I took the valve cover off and all of the tappets move when cranking and the ones with no pressure on them move freely but it is really sludged up under the valve cover. I will end up pulling the head just to see how bad it really is. I have another motor that came out of a pulling tractor that will go into this one until I decide what to do with this motor, might be better off to part it out.
