Spray gun dripping

[rnt80]

My Asturo gun is dripping finish from the tip.  I've cleaned the tip and the needle thinking they weren't seated correctly.  I also stretched the spring out behind the needle.  Neither of these fixes worked.  Any suggestions?

Do you have a different set you can throw into it? I am sure if you did, you would have already, but good to eliminate the obvious.

Either something is hanging up the trigger, the product is way to thin for the needle/orifice, but my guess is the needle is worn and no longer seating properly. They do wear out, finish is more abrasive than most realize.

Do you have the right size nozzle?
Or maybe dirt or broken tip?

Scott, I haven't done the obvious yet.  I have a second, different sized tip and needle set that I can throw in there.  The finish can't be too thin for the tip size.  I've never had this problem before so something has changed.  I suppose the needle could have worn down, I've never thought of that possibility though.  I am no finisher and so much of what I know has come from mistake after mistake.

Same here. I have to make the same one a couple of times before I forget.

Tom is right, materials are surprisingly abrasive when pressurized/atomized, etc.

Hope its a simple fix.

I mentioned the way to thin because I had the #6 set in my gun. Wanted to do a quick test, the needle would not hold the fluid back once the up was under pressure. I put #3 set in and was good to go. Glad I had the PPS on the gun, otherwise it would have been a real major mess, instead of a major mess.

Yep, sprayers wear out relatively quick. You have to replace the important parts once in a while.
