Oookay. Called Jack's Small Engines and they didn't know, just that the B&S schematics showed the parts I had were compatible. They suggested I call the B&S technical line, which was my next call. They came up with the same info, that the crank and rod I had were correct for the application.
So I played around with some parts diagrams and model numbers and came up with the next likely candidate. Gonna try 794122 as a replacement connecting rod, it's on the way. Thanks for all the help, will post up when it comes in and we get this figured out.
