Heya, Folks,

I have a trigger-type Tamiya HG airbrush. I make a point of keeping it very clean, but nonetheless, I have a new and recurring problem:

When the needle is seated all the way forward, as it should be, my airbrush will not shoot paint --- only air. The only way around this is to pull the needle back a bit, but this gives me splatters...

I have run thinner, airbrush cleaner and even Simple Green through it, have repeatedly disassembled it and soaked it. The best I get from that is that it sprays fine for a a few minutes, then the same problem reoccurs.

Any ideas or solutions...? This is very frustrating!

Thanks, folks!

Much Aloha,

Johnny B.

Hello Havoc

I don't have that type of airbrush but I have had a similar problem in the past, and it was usally because I didn't have my paint thin enough.

not sure if this helps but thought I'd throw it out..

good luck

P.S. the rule of thumb I use is to start off by thinning the paint to the consistancy of milk.. then going from there as needed..

I have an Iwata and this may be like comparing apples and oranges. With my airbrush, when the needle is forward and seated against the nozzle no paint should flow. When I pull back on the trigger my needle moves back and paint begins to flow.

The spattering sounds like the needle tip/ nozzle may be bent or the paint is too thick.

When it paints fine then starts to spatter after a few minutes you may have tip dry. This is where the paint dries on the tip as you paint. Clean the tip frequently or add a drop of paint retarder when you thin your paint to spray.

Cheers
Greg
