I also have a NGH 25. It looks to me to be a better engine.
I'm a little confused about one thing. Did you buy the ring and receive the note from Frank Bowman or Joe? I have seen pictures of some "flashing" on the internals on some engines. Especially on the reed cage. I've had my DLE20 apart for repair and inspection. I did not see any areas with flashing that needed to be cleaned up. On the DLE20, the reed cage is a polymer and had no areas that needed to be cleaned up. I love that little engine. I think I'm going to try a Bowman ring in it, as well as possibly testing out a "velocity stack", just to see if the engine runs any smoother. I'm not sure how I can really tell, because it runs so well already. But I like performance upgrades! I think it comes from me always tinkering on my cars (superchargers, cams, rocker arms, etc...).
As for NGH engines, I'm not a fan of the carb location on them. I've also read a lot of negative things about that style carb configuration. Seems like they need some modifications to make them run as they should...
Oh, and just fyi...I realized I will be on duty friday and saturday, so I will not be able to get my hands on the engine until I get home sunday...
