I picked up a 1976 Sears SS16 a couple days ago and it came with a "spare engine", apparently the engine that is in the tractor is the wrong engine and the spare is the one out of the tractor. The manual for the tractor says it should have a BF-MS/2666C which is the spare and the engine in the tractor is a BF-MS/2833E.
The PO said the correct engine was re-ringed and valve guides and valves were replaced about 100 hours ago but then if that is true why isn't it the one in the tractor? I ask myself. When I asked the PO for engine numbers a couple of months ago he sent me the ones for the spare engine not the one in the tractor.
The only differences I can see from the outside is the points style and "points box". The deal came with a set of points and a condenser that fit the 2666C set up. First question is can I take the points box from one and put it on the other one and call it the 2666C?
The deal also came with a brand new carb (box says part number 142-0663 which is supposed to be the one for the 2666C engine) but the new carb does not have the built on fuel pump but I also got a new Onan fuel pump (part number 149-1982) with it. The receipt for the pump was in the box and sold in 1996 for $45.51. The carb is listed on the Sears part site for $500 and change. Second question is can I use the new Carb with the new fuel pump?
In the box of parts there is another engine pulley that has the same diameter inner drive pulley but the attachment outer pulley is about an inch larger in diameter. Third question which is the right one? I did forget to measure the crankshaft diameter so maybe that is why there are two.
I bought the tractor to run the Roto-Spade that came with so it's being 100% stock is not an issue. I just want something to work. Heck I have even looked at pulling the B&S 18 Hp opposed twin out of the Craftsman and putting it sideways in the SS16.
I can get photos tomorrow if that will help.
