Cute as a button, it's heavier than it looks but much easier to handle than an LK.. I will probably take off the stator for a better look at that area. Both sides of the engine had a good coat of grime and I need to make sure it didn't come from the rear crank seal, that's that last item I need to check. This model AJ doesn't have an oil pump, dipper splash lubed, but the crankcase breather check valve was stuck.

Got lucky on this one, dirty but was stored is a relatively dry location and I don't think it has many hard hours on it. The CK I just bought was stored poorly and has more rust and dings.. Will need some parts, power tools and paint.
