Manifold Pressure Gauge

[coloradobluesky]

The Manifold Pressure Gauge in my Husky isn't working. It seems to just stay on the airport elevation pressure the whole flight (might move a little). It started by getting sluggish. Any chance of repair or do I just replace it?

Any chance the line feeding it is defective? That's a fairly common failure.

Yup. Probably just a loose fitting on the hose or metal line somewhere.

If it stays at airport elevation pressure for the entire flight I'd suspect the needle is stuck. Unless you're flying at low altitudes all the time (which isn't out of the question in a Husky), you should see a loss in pressure as you climb in altitude. Remember, you should lose around 1" per 1000 feet.

But, if the pressure is actually fluctuating with altitude then I'd go with what the others have suggested.

Maybe stuck a turbo under the cowling?
