OS FS-40: First run after rebuild!

This post shows the first run after rebuilding this engine. It really is a sweet engine. It may not be a powerhouse by today's standards or even in 1981 when it was released, but it is a very good running engine. It started on the first flip. This engine did take some considerable prime to get started even on subsequent I have done. Unfortunately, the age and low power do not make this a very attractive engine to most folks in the glow market today. Everyone seems to value absolute power now over high quality. It is my belief that the quality of this engine is unmatched. In mind, this is an example of the pinnacle of OS quality as are all of their engines from the 80's through mid 90's. As such it will not be sold , plus it being a gift to me, it has a bit more meaning and value.
