Airspeed Indicator problems

The original Schweizer airspeed indicator in my glider sticks.

The pitot line runs to the bottom port on the back of the instrument
but not direclty. It has a tee that routes it off to another
instrument also. I would have thought that the pitot should have an
uniterupted tube going directly to the airspeed indicator.


Any advice would be appreciated.

I agree with the other posters---send it in for cleaning, and calibration.

The tee is probably to a netto cappilliary, or possibly to a hidden
diaphragm TE compensator.

A 10 cc medical syringe is a good "air pump" for testing systems.
