Peter in Belize,
The point I was trying to make was that the combusting gas when exposed
to the incoming air fuel mixture would detonate in the inlet manifold, and if
this did not result in explosion, it would deplete the fuel from entering in
the cylinder denying the engine power for the next stroke. Two strokes have
never been used for naturag gas firing have they in spite of the fact that
most are in an acceptable compression ratio to be used on natural gas.
Cummins and Cat both use the diesel blocks for natural gas engines,
changing out the compression, injectors for spark plugs and electronic
ignition for injector pump where applicable.
I don't think converting GMC 2 stroke engines will work.
