[Shop-talk] Quincy 310 compressor guru needed

[john niolon]

I've got an old Quincy 310 compressor that is giving me trouble. As it builds pressure the unloader valve released and it won't
build over 20# of air... If I remove the copper tube from the pilot valve to 
the unloader it will build up as it should but I have an 
air leaking out not from the copper tube


so it cycles a lot... pictures can be sent and I'd love to figure this out soon

thanks
john
