[SEL] old engines on Propane question

[Harry Terpstra]

On the IHC Famous, we'll make a flange that will come between the mixer, and
the manifold.
It's about 12mm (½") thick, and we make a jet in the flange to hook up the
propane.
Works real good. We start on propane without much effort.
When cold it's isn't running that great, but as soon as it warms up (after a
couple of minutes) it runs real nice.

We use it on a 4 or 5 engines. A few of them because on gasoline they are
dripping / leaking very much.
And our Witte headless, and the Monitor because on gasoline they get very
dirty. Mainly because they have a (pre) combustion chamber.
