Back working on my 1967 Kohler L600 flathead 4 cylinder engine. I bought it all new valves because the old exhaust valves were trashed and the old intake valves had rust and pitting. The book calls for the valve guides (cast iron) to be .312 - .313. One of the exhaust valve guides is on the upper edge of that, maybe .3135. The exhaust valve will have .005 clearance, and the book calls for .0025 - .004. So, it is about .001 - .0015 over spec. If it makes any difference, the engine has tappets that push directly up on the valve stem, so that there is no side loading whatsoever. It is an 1800 RPM engine, so it runs relatively slow. Also, since it is an exhaust valve, oil consumption and vacuum leaks won't be a problem. My guess is that in short order, soot will coat the inside of the guide and tighten it up a little. The guide is still available for $20 if the YT brain trust thinks I should replace it. I don't really want to replace that guide if I can avoid it. What do y'all think?

The generator was shot as well as all the wiring. I dropped off the tractor expecting a transformation from a 6 volt to a 12 volt system utilizing the original generator housing, and a total rewiring of the whole tractor. The front end center pin bushing was worn also so I ask that they replace it if they had time. Well, that’s wha
