I figure the dumbest questions are the ones you don't ask so here goes...New to all of this, have an Iwata HP-CS, regulated at 35lbs with a mac valve and separator in line. When I dial the pressure down to like 15-20lbs, I get an initial hard hit of air that sometimes throws a splatter but is definitely NOT something I want near the piece I am working on because it would be a big splat. Do I have something setup wrong. Needle and tip are clean. California compressor.
