Yup. Cap, rotor, points, condensor, plug wires (solid core), plugs (D18's) are all brand new. Distributor shaft seems to have very little slop. I checked. I double checked the points. Engine starts almost instantly, but idles rather rough. Very consistent in its misfire, as if one cylinder were not doing its share of the load. That's why I started thinking valves. A flakey carb or governor would not be as consistent in the misfire. Also, she's very constant in her speed. When I set the speed, she stays there, even if I get to lugging some steel beams with the front loader. So again, I'm not thinking governor or carb.

I just bought the tractor in October or November, and I'm pretty sure no one has had the valve cover off in years and years. Two owners ago was a collector who never got around to doing anything with it. The guy I bought it from was a guy who used it a couple years for doing gravel driveways. Then, he got a tractor that was easier to move from site to site, and let this one sit for a time. I doubt he even thought about the valves, let alone set them.

I figure that setting the valves is a maintenance checklist item. Have not checked compression. Not a bad thing to do this afternoon. Getting the valves set right would affect compression, wouldn't it?

I could switch to D21 plugs, but that should not make a difference when they're new. That would only make a difference over time, fouling or burning the tip off.
