Have to compare a gas and diesel with identical ports, manifolds , valves and the biggy, CAM timing. The diesels have very short cam duration and valve overlap . That they build lots of cylinder pressure at low rpms but fall on their face and starve for air when reved up. Can"t put a gas cam in an ordinary diesel as the valves will hit the pistons at TDC . If the pistons had deep enough valve reliefs cut to allow long duration and overlap. The compression and expansion ratio would drop to the point where cold starting would be difficult. We all have seen these long duration cammed diesel puller engines that make lots of high rpm HP. However starting requires a high powered starter, pull starting and/or a snort of ether. The compression ratio is low due to cam duration and high manifold pressure.

Today's Featured Article - On the Road with Dave Gohl: Tractor Club Beginnings - by Dave Gohl. I was surprised about a month ago when I got a call from a fellow tractor croonie. His message was interesting and to the point. He's says "Dave, I've been thinking about starting a Two Cylinder club for our area. What do ya think?" It was a loaded question. I said that I would be interested, and was wondering what his next step was. (Although I was talking under my breath, since I thought of this some years ago) My friend, Arlyn Lamb of Lakeville, Minnesota was sincere in his miss
