It looks as if you may have tuned in late. Bret is planning to use an air
cooled Deutz engine, out of a wood chipper, that he got cheap because the
previous owner had cooked it.

That's what I'm talking about, trying to make power under lugging
conditions. The Jeep gearing may be low enough to avoid that, but I don't
know the Deutz power band myself. Cylinders can get fouled with dust too,
if there is the slightest oil leak. Typically, you would have to traverse a
few miles of gravel and/or dirt road, to get to the rocks. Is it practical
to give the engine a bath, once you get it dirty?

That's what I'm talking about, trying to make power under lugging
conditions. The Jeep gearing may be low enough to avoid that, but I don't
know the Deutz power band myself. Cylinders can get fouled with dust too,
if there is the slightest oil leak. Typically, you would have to traverse a
few miles of gravel and/or dirt road, to get to the rocks. Is it practical
to give the engine a bath, once you get it dirty?
