Aerothrust Pormo Ins and Outs
the flywheel...


AOMCI member and Aerothrust mavin, Richard Hiiuvain, explains:

Working on a Pormo stationary Engine today I decided to remove the flywheel before moving it to the basement as these motors are a 160 lb beauties.

If you notice inside the flywheel there's a spring which I believe acts as a damper.

There are governer cogs. These open to push a rod that go through the block and moves a lever on the intake.
