Got into the 124 tonight. Pulled the head and found a little carbon buildup

. Looks like there was a little blow by so I'll need to address that. Any recommendations for the valves?? I'll get it'll all cleaned up and see what they look like. It was running good so I don't want to dismantle any more of it. Also took the rear apart some more, pulled axle seals, bushings look to be in very good shape. Will need to clean out gear box as its got some crud in the bottom of it, but looks good otherwise

Pulled brake pads and now just need to start ordering new parts. Was hoping to sell this tractor when I'm done with it, but I don't know
