Hi Bruce...Visual appearance makes a big difference to some people...A Rossi .40 is sandcast and beadblasted on the outside but is like jewelry inside, and it runs like it...
Some people like the red paint on the Air Hobbies engines......
You don't EVEN want to see the inside of my shop

Some of the FPE engines were timed about 10 degrees retarded, that's what I fixed on yours....
I'm going to find some black wrinkle paint and do a G26...Wrinkle on the cases and cylinder and polished fins and hub..It will then look as good as it runs....
Hey, maybe then I can charge $500
