Nope, Scotty, the serial number was clean and easy to read, 386**D, and the "D" is definitely a "D". There are prefix letters stamped together in a straight line (machine stamped?) in the top left corner of the planed area- "FCM" or "FMC", one or the other, can't recall exactly- could this be a replacement-ordered block?. I haven't been out yet to check on how the pump is mounted, but it's in the normal position and all, so is it possible that holes were drilled and tapped on an older block? (Was there room for this on the original A block?) A lot of trouble, true, but who knows what people did on these things in five decades.
As for the governor, yeah, that's what I'd planned to do, and I think the shorter spring is toward the front, so meeting the adjustments halfway would be next, I guess. I think I'll crank it up and try it out before I do anything else, just to see how it runs and what the range is. Before, the throttle lever would go back enough to kill the motor (restricted fuel flow?) and seemed to "top out" before the engine revved quite as high as it seemed it should. (Yes, I know they don't rev really high.) It's strange that there would be as much difference as you mentioned in the effective range of the throttle action on individual tractors, especially when the mechanics are so basic and supposedly the same; I don't doubt you at all, it's just weird.
So it's back to the tinkering again. At least the belts are on and everything is spinning, so I can crank it and check things out better. I really appreciate you sticking with me on this, Scotty, it sure makes it easier to dive into rather than going into a system completely blind. I've never dealt with a governor on an engine before, but I guess it's aptly named; it's placed between the working man and the power in order to control that power and it doesn't always act like it's supposed to or do what the working man wants it to do. I hope I don't have to impeach this one.

Today's Featured Article - Show Coverage: Fair Weather Tractor - by Dave M.. No, Fair Weather isn't some rare brand. It's the kind you can't leave out in the rain. Here's how it happened. I had been casually looking for a tractor for weeks. I saw a few 9N's, but they had even fewer amenities than the 8N my Grandpa bought new in '52 with a Dearborn loader. That was 10 years before I was born, so I grew up thinking that 8N was the world's best tractor. Grandpa had greenhouses, with over half an acre under glass, and that 8N did almost everything. It was the only
