brand new North star 2 hp 5.3 cfm
after break in run I noticed that the two air filter covers have a port to feed fresh air into the compressor.
Problem ? the filter port on the right has plenty of vacuum the filter port on the left has very little vacuum .
Could this be normal or is there a problem.
Seems to take some time to build up pressure ,
I am wondering if this is normal or what.
Thanks forum for any answers.
