Hi Folks,

This weekend I took some photos of a 13b installation in a polywagon.The

installation is done by

Jan Kemp.
First  photo;
  Right hand view, Note the header tank mounted on top of the engine.
Second  photo;
 The radiator mounted on the belly. Note, no fairings leading air in or

out of the radiator. Runs

cold even with full power ground runs.with a ambient of 27degrees C.
Third photo;
Left view, The carburetor is from a Cessna 175, the manifold is split

from the carburetor base to

the intake tubes to prevent heavier fuel-air mixture being thrown to the

outer side, causing the

outer rotor to run rich.and yes the exhaust is noisy.
Fourth photo:
Note the offset (1degree)  And about the lack off a carrier bearing ,Jan

recons his previous

project had a rabbit engine, off which the bearings are a third in size

to that of a 13b bearing,

and that ran fine for ten years.

As I recall, the Polywagen was designed around a Volkswagen engine, and has
a rather limited tail volume coefficient. Y'all be careful out there - Vance
