yeah i saw the parts list, but im not looking for parts. Im wanting to buy a spare engine that will fit my current mower. Im wanting to beable to find the bolt patterns, shaft dia. etc for a given engine. I just haven't found that info on older engines. thanks
Well, it looks like your engine is a fairly typical Briggs I/C internally balanced flathead. They didn't change too much over the years. The bolt pattern should be the same for later models than yours. If you're looking for a replacement engine, you just need to make sure to get the correct shaft size.
