RE: Stihl 65cc "Four Mix" four stroke engine
VERY nice. Glad you are finally getting some good use out of that engine. It sounds great!!
Darn it, now you've got my (already high) interest increased to get one flying myself! I sold two of the 32cc Stihl four strokes to guys and they are quite happy with them. I have a 36cc that I saved for myself and am just waiting on new rings to finish it up. Plus I have a couple more 65cc four strokes to do. Too many projects!!
Anyway, looks great. Like you said; a lot of power too, but that sound..... I can just see/hear one in a Fokker D7, or another oldie favorite of mine, an AVRO Triplane!!
Note: Your title is wrong. It is a Stihl 65cc "Four Mix" four stroke engine; not Echo.
