I found this rather information packed web page on the 20B that may be
of interest to members of the list. Even has a parts and price list (Yen)

Interesting site. The link at the top jumps to "20B AEROPLANE ENGINES."
There are 3 engines pictured. The middle one is an Atkins modified 20b which
is not for aircraft use, but is for an air boat. Yes, it drives a prop, but
notice
that big black pipe in the back? it is the return for the water used to
cool the
engine ... water that comes from and is returned to the lake. Not that great
for aircraft use. Dave Atkins does plenty of mods for aircraft, but the one in
the photo is not.

Also listed is the address for Grant Nichols in New Zealand. That is where
I got
my 20b, but if I had to do it all over I would just buy one already rebuilt
from Dave
Atkins. It would have been simpler and cheaper.

Cheers,
David

The first picture is of Chuck Harberts engine taken at Arlington. I have more
pictures.

That big black pipe in the second picture is a water cooled exhaust manifold made 
by Rotary Powered Marine and is often required by the US Coast Guard. That engine 
is supercharged and not turbo charged. I have more pictures.

BTW Rotary Powered Marine has an engine in a radical boat called "Outrider Flying Boat"
pictured on page 91 of the March 2001 issue of Popular Mechanics. Congradualtions Jon good
PR for the rotary. http://www.klemflyingboats.com/ there is also a link on the
ACRE NL web site for Rotary Powered Marine.

The third picture of the Racing Beat engine was taken by me and published on this 
news letter awhile back. Craig is on the list. For more pictures of this engine
check the ACRE NL web site below.
