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.

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
