Thanks Al, I grew up in Hookstown about 24 miles from you, that makes the second high compression .80 I have and I also have a very early High compresion 1.50
I ran the new, ( to me anyway) .80 today, I tried a Graupner 12.5x6 first and a MasterAirscrew K-13x6, by the way it came with my favorite plug a Fox Miracle Plug. The tiny O-ring in the end of the spraybar was missing so I installed one.
Fuel===WildCat 15% 2/4 stroke fuel
Graupner 12.5x6======10,550 rpm
MA K prop 13x6=======10,150
I used a later model muffler like the .91s came with, the thin walled aluminum cans.
It runs really well, I may upgrade the spraybar to the later spraybar.

Jim, The engine has a Q on the right mounting lug.
