[Shop-talk] Quincy 310 compressor guru needed

[nick brearley]

I'm by no means a Quincy guru but this year had similar problems with an 
ABAC compressor, The cause turned out to be the tank check valve, 
resolved by cleaning. This site proved very useful:

https://fix-my-compressor.com/compressor-tank-check-valve/

Most compressor related problems are covered and I found the site worth 
bookmarking.
