Just the flaps, man...
First thing that caught my eye was that the flap on the left side was not installed properly - it's backward. The clue was that the end of the tiny bolts was making contact with the top of the inside of the fan shroud - preventing the flaps from opening all the way. The flaps, oddly enough, were designed with this in mind - they're made to be flat on the back side and have an inset area for the screw head so that they do not foul the fan shroud. It's a fairly small detail but anyone building engines for more than a few years should know this detail because it affects the proper operation of the flaps.
Again, anyone who has built more than a handful of Type 3 engines should know this.
Yet another reason that outsourcing Type 3 projects and work to others can be a frustrating experience, to say the least.
I've also come across the 'eyeglass tin' from the engine and have noticed that it's not dual carb tin, rather it's for a fuel injected system. The top of the tin is flat for carbureted engines and has a raised section at the top for fuel injected engines. It does not fit quite right over carburetor manifolds.
For what I paid for this engine - there's a lot that's not right, places where shortcuts were taken and attention to detail was seriously lacking. It's disappointing, to say the least.
