The engine has been completly disassembled, and most parts (that needed it) have been sandblasted. The mixer and bearing caps are left. I don't know yet what I will do about the mixer, it is REALLY RUSTY. The following photos are some of the major parts.
The main casting is sandblasted. I removed everything, and masked off the bearings, each end of the cylinder, and sparkplug port. I think I picked the hottest day of the year to do this - it was pushing 100 deg, and hi humidity. I will probably go over it again, just before priming. There are a few spots I missed, and oil is seeping out in a few others. I want it to be super clean before priming it.
The con-rod end of the cylinder was plugged with a piece of foam that I cut on my hot wire cutter. It worked great, and I will use the same approach to plug it when painting
Both flywheels are done, and both exhibited what appear to be sand holes in the casting near the hub. (see closeup on the right). The holes had been plugged with putty or something similar. I will seal them with JB Weld or PK-7 epoxy. Was this common in Stover castings?
Here is the head as it now looks. Again, all holes were plugged and the face was masked. The head apparently cracked sometime in the past, and was brazed. I ground the surface of the braze flush (it protruded quite a bit from the surface), and used a little bondo to smooth it out. After sandblasting, a pitted surface resulted, which should completly conceal the braze after I paint it..
