Rebuilt Flathead Problems.

[Frank Miller]

I say these are nothing more than glorified lawn mower engines but even those have gotten more high tech. There are some flathead nuances that a rebuilder should know about, such as grinding a radius on the crank but this is a real rookie mistake for anyone who knows how to assemble an engine. If this guy were building an interference engine he would be paying big bucks to fix it. I do not see this as lack of knowledge as much as sloppy workmanship.
