Thanks for sharing Jim, 4 stroke gas engines are my favourite among engines. I have a roto 85fsi coming very soon. I wanted a multi cylinder 4-stroke for my yellow P-40 and the roto is the best size for it, my second choice was a valach 60 but i wanted atleast a twin and the roto came up here on rcu for $1000 nib and couldn't pass it up.

keep sharing your experiences, Mike
