The engine was originally a Gilbert Duty
Hi Dan
I have not heard the name Duty in quite some time. My original engine was
also reportedly a Duty engine. I hope that at some point in his career of
engine building that he put together a good engine. Mine was built as a
2000cc, the builder used the cheap aftermarket cylinders that were paper
thin and one of mine cracked in the air. I also have a prop extension which
is 2" My prop hub came with the engine and takes the place of the front
bearing. That part worked well and I reused it on the second engine.
