Help please. Newbie at airbrushing

[Hockeyboy76]

Having been a brush painter all of my modelling life, I thought I would try this airbrushing lark. I have a 1/35 Tiger tank to paint so have bought an airbrush that runs off propellant canisters. I have set it up right according to what little instructions there were, thinned the paint ( Mig Ammo acrylics with Mig thinners at a 50/50 ratio, but when I push the airbrush I get a quick burst of air which then fades off to a constant stream but no paint. It only seems to go up the tube on the initial burst. The valve is fully open on the canister. I'm at a loss. 

Anybody have any ideas?

Loss of air pressure due to the can getting cold very quickly.

Stand it in a jug of very warm - but NOT hot - water; that should help

What BK says/ However,try spraying a small amount of water first=if it sprays ok you are good to go.If not you have a blockage somewhere. Sounds like a single action brush.siphon feed. You might want to consider adding Winsor and Newton flow improver. a drop or 2 will work wonders, but only when the head is clean and completely clear. No airbrush will work if clogged with paint and acrylics are notorious for doing this.

 

HTH.
