Nice engine,and very well done. I believe that engine is similar to the Seagull, from Hemingway,
is it not. I'm still learning some of the many engine plans. which I never knew were around. Again
nicely done!
Hi Ron
Just to confuse the issue a little more, I believe the Seagull came out in both a air and a water cooled version. (both are side valve engines)
