This is a poppin' johnny.
need another history lesson?
is what them was called.2 cylinder that made a distinct sound of its own.i have worked on a few of them.
They were in widespread use by the farmers when I was growing up.
Start them on gasoline, when the engine was warmed up, swap to the main tank of kerosene.
Never had a G. Did have an A, 2 B,s an H, a 520 and a 630. Nothing runs like a Deere!
My oldest sister & Brother in law used to run a dairy farm in WVA, They had one. His brother has it now.
My neighbor had one and you could hear him comin up the hill. He had a woodlot behind our pasture.
Ww bored out the cylinders in on of the B's and put pistons as big as your head in added larger tires left over from the A. Talking about a hoss! There wasn't a tractor around that would touch it.
