This is very exciting Scott! What about bearings? Can it be ordered with a shorter prop hub? Very impressive, I'd also like to see how it might respond to a pipe.

It is for the CS 520. Twin ring, domed piston. I wanted to use an engine that will be available for a long time. I did not want to run into problems with getting them like some of the other engines I have done and had to drop. I talked to a rep from Echo and this engine will be around for some time to come.
