28/2/11 Unidentified Engine Q. See two photos of a very unusual opposed piston engine. I lost the directions on this engine, but as I recall it was in Minnesota near Hill City, owned by two brothers. Any information or whereabouts would be appreciated.

Recently I acquired a Carlisle-Finch engine. Obviously there is something missing on the valve structure mechanism. Is there anyone out there in engine land that can help me out on this little jewel with pictures or information, please? Harold Gaddye, RR 2, Binbrook, ONT L0R 1C0 Canada.

28/2/12 Leaded vs. Unleaded As an enthusiast to both older truck and tractor restorations, I am a subscriber to both this magazine and Hemmings Motor News. From reading in the latter, it is my understanding that they have taken the position of using unleaded fuel in vehicles.

In my opinion, GEM needs to take a similar position (for a healthier environment) regarding stationary engines and vintage tractors.

I recently had a 261 Chevrolet truck engine built to burn unleaded gasoline. It turns out that the old method of repairing a valve seat (that is, grind out the old, damaged valve seat and knock in a steel seat) has become the way to use unleaded gasoline in the 1990s.

Sure, it takes extra effort to put in twelve steel valve seats in a six-cylinder engine such as the Chevrolet 261, but for a better environment for us and our children, it has to be done. David Cade, Box 53, Chapman, KS 67431.
