You don't want to know.
It was a package deal with the tractor.
Seller said it was missing a spring from the carburetor. I'm not sure where, because it runs and governs just fine. The choke rod is missing a nut, I think, and the choke mechanism may be where the spring was because I had to hold the choke open while it was running. Honestly, I think I'll just put a spring on to hold the choke open and just manually actuate the choke when I need it. It originally was linked to the throttle so when it was beyond the fast position it actuated the choke.
As typical for Briggs, the one-way clutch on the recoil needs a spot of oil because it shrieks at random times. Easy fix.
Engine runs, tines turn - if I had a tractor set up with a sleeve hitch I could be turning ground over in a half an hour, I'm sure. The previous previous owner had fabbed up a place to hook the tiller to the back of the tractor but it was nothing like a proper sleeve hitch and didn't allow for any lifting or lowering.
I got some pictures, will add them later. Working on the tractor, now. The solenoid for the starter isn't engaging.
