Nice rumley!

Do these run as a diesel or are they hotbulb semi-diesels?

[Rumely1630]

Nope they have a magneto and the later ones such as this have spark plugs. Here we are burning a mixture of Gasoline, Diesel and Water.... Although at a light load it doesn't draw much water.

Thanks.

I presume the water is sprayed into the cylider to help keep it cool?

The water jet is in the carburetor to keep the diesel and/or kerosene from detonating because of their low octane rating.

I see now, many thanks.
