What about "flywheel drive"? That allows any prop, (even a redrive?), puts the
stresses at the stronger bearing. Any downsides? too big to make a correct KR
cowl for it perhaps? Overkill? 158LBs is light.
Thoughts?
FROM GP AIRCRAFT ENGINES:Why Flywheel Drive?
The flywheel drive drives the prop off the #1 main bearing. Many builders
consider this the correct way to drive the prop on a VW (it's only one of three
ways and we can't say one is better than another). It offers a lighter engine
at 158 lbs., and the least expensive way to drive the prop on a VW engine. Even
with the oil pump secondary ignition (which adds $799.95 to the price), it is
the Lightest and Least Expensive 76 HP VW conversion offered in the market
today!(Note: when set up for a pusher - the flywheel shims remain between the
flywheel and the #1 main bearing. When used as a tractor the end play shims are
moved between the crankshaft and the #1 main bearing.
