Hi hope you can help compressor stalling when out let valve open.

When closed is not making pressure like does normally

The unit is an old one cannot even get a manufacturer

Any help at all would be a great help as I am out of ideas

PS I am a mechanic but with no real exp of compressors

Pix might help ID the thing...

So it's idling OK?

Then you're looking at either a cable or air line (to an air cylinder) to the throttle , which is supposed to open throttle for air demand, based the low pressure caused by opening the outlet.

That's assuming the engine is basically sound, of course.
