[QUOTE="William Adams, post: 238942, member: 17783"] I started by spending some time checking the important stuff, namely drivetrain health. The engine "looked" healthy. Other than the suspicious black color, it appeared to be 100% stock. I read somewhere that CC replacement engines are factory black? Anyway, after fiddling with electrical bits and replacing the carb with a knockoff, it fired right up and sounded perfectly healthy. No smoke, weird noises or foibles. I tested the hydrostatic transmission and it went forward/reverse without issue. Pretty quiet for a hydro in my experience. As I had already mounted the chassis on my improvised roll around cart, I couldn't test torque output but it seemed reasonable to assume it was generally serviceable. I pulled the relief valves (actually did that first before testing g) and got them to pop up from their stuck down position. Pretty easy... I also pulled the differential top cover for a look at the all important spider gears, bearings and ring gear. The oil, though low, (she's a piddler!) Looked clean and cared for. Gear tooth wear was indicative of a well cared for transmission. [ATTACH type="full"]147633[/ATTACH] The transmission downside (so far) is that the external trunion shift linkage is dreadfully worn at all bushing points. Lots to do there. I spent a lot of time that I won't relate here getting all of the unneeded bits (front axle, steering column, mower mount, etc) removed. The chassis, while it looked pretty good, was actually pretty rusty. The frame is fine, but the instrument panel tower, hood and rear panels were pretty crusty and, around the battery box, partially gone. No problem. I'm a sheet metal guy, among other skills.
