I picked up an old Bolens 726 off Ebay last summer. The engine is a Tecumseh H70 made in 1976. The blower was in pretty good shape- still had factory paint on the augers. [the shoes had never touched the ground, though- so the bottom of the scoop took some abuse and needed a bit of welding]
I've been tinkering long enough and finally have it almost ready for work. The differential has me puzzled, though. It has two little tubes, maybe 1/8-3/16" outside diameter, coming up from either end of the axle. There are screws plugging the ends. I'm guessing they are there to add/check fluid levels, but I don't know how much of what fluid to put there. [if any]
The differential has a big cast iron 'wing nut' on the right hand wheel. I can take photos if necessary.
Thanks,
Jim
