Phil;
I don’t know what mounts there in
the auto application, but there is no hole through to the inside of the rotor
housing. Just leave them open; or, if you find it convenient you can use them
to mount something.

Subject: [FlyRotary] 20B - holes
above plugs
Bill, Tracy:
I have just now noticed that the 20B rotor housing has a treaded hole about an
inch above the upper spark plug hole. There appears to be a small hole at
the bottom into the rotor chamber.
What is this for? For aviation use, should it be
plugged? If so, do you know what size thread is needed?
Phil
