    Well, I took the gun apart again, worked with the regulator a little, and put everything back together. The paint now flows consistently..sort of. It seems like the air pressure has to "ramp up" for a few seconds. Sort of a waste of paint if I have to deal with that, but once it gets going, it appears to spray just fine until I let off the trigger for more than a couple seconds.
    That said, I haven't tested it with anything other than water just yet.
    Anyone have a high quality in line regulator to suggest? I'm assuming the one that came with the gun is pretty low quality.

    Just don't invest so much money on this gun, that you will realize you spend the same amount a.n.i. 150 would cost. It's 100 bucks my place:

    What are some of the options in the USA for the $100 to $150 range on a detail gun? (would also help if there is a 4oz cup option for a given gun. I find it unlikely that I'll ever use more than 2oz for the size area I work with. Although if I get to the point where I need something more, I will be able to afford something different anyway.)

    All I use is Window Cleaner without Amonia and Thinners Grade A for Automotive Paints.... 80% alcohol is good perhaps mix with Windex Ammonia free window cleaner will help... remember I am new... that is what I wouldve done with limited resources....

    I ordered a couple from Spraygunsdirect to the US and it was the fastest shipping I've ever seen. 2 days to my door from the UK. Insane. I can't ship a package from one state to the next in two days.

    Little late here but that 4oz detail gun is one of my favorites, a little tuning and it will spray nearly as well as any mini for $15
    I use them all the time.
    I did the vast majority of this with one.
    http://www.airbrushforum.org/threads/quick-portrait.19454/

    Run it only about 25-30 psi
    Heres your possible issues in order of likelihood.
    1. Regulators ( my money is here)
    In short, crank your comp reg all the way up, open up the gun reg and use only the inline to adjust.

    Assuming your small compressor has the usual small regulator.
    If you want to run one at the gun, the one at the compressor needs to be set wide open. Each one restricts volume as well as pressure. Also you'll want the one in the handle of the gun wide open. Personally on a small compressor I run only the one at the compressor and i set it at 30 then choke down a bit w the guns built in reg.

    Basically
    In general each Successive regulator used in a supply needs to be the next size down. So if you had a big industrial reg at the compressor then you could use an inline, and so forth.

    2. They use glue in the threads and alot of times there's too much. This is almost always the culprit for one that has a non-working fan adjustments.

    @Robbyrockett2 The compressor I have is a CA Tools 15020, and the regulator would be the one that came with it.

    I'm still trying to find a solid regulator to put between the compressor and my airbrush & spray gun.

    This is important especially if the spray gun only needs 25 to 30psi, as I run the airbrush at 30 to 35.

    That and I'm not sure how much the air hose is affecting the pressure at the guns. I need to get a new air hose also. The one I'm using, while it has no leaks, is about 20 years old, and is 50' long.

    The inline you have should be ok but you'll have to set the regulator on the compressor all the way as high as it will go (screwed in all the way ignore the reading), then adjust the inline to what you want.

    You can't use that type regulator on both ends.

    If you set the compressor one to 40 and inline to 30 you will never have enough volume to run a gun. You'll also get some odd pressure swings.

    Alternatively, ditch the inline, set the regulator at the compressor to 40 then fine tune by ear with the knob on the bottom of the gun handle.

    This will be true with any regulator you get by the way

    Just an FYI for gun cleaner that works awesome, check out Naked Gun by Kleen Strip. That all i used on my guns for when i spray yachts. Comes in and aerosol with a straw and you can easily clean with no soaking.

    That sounded like a commercial...:thumbsup:

    Thats pretty cool! I wonder if you can use the non-aerosol version in a still type recycler

    I also just realized you probably have the silver color 4oz touch up gun/w .8 nozzle and not the little purple k-3 .6 tip 4oz gun that i really like. I dont like that gun at all, falls apart quickly, hard to tune in
