Please post a pic or two!!!
Congrats, it is allways an accomplishment. ANd the AHC is not the easiest small engine to machine either...
Just a question, did you manage to get a stamped backplate or did you machine one? If you didnt get a stamped one I may have one you can have... (have to check, I am really not sure!)
I got a few of them when I got the AHC castings.
