Unstable Paint Flows on My Airbrush

I am new to airbrush painting, so I bought cheap single action Badger
with propellant cans sort for testing it out. The whole package only
costed me
$35 or so.
I found that my paint flow is very unstable even though I have not
anything. Almost every time I press the trigger, tha paint volume is
different than the previous. Recently there is mostly only air, no
I have checked everything I could, nothing is obviously wrong to me.
The nozzle appears to be clear too, as I can blow air thru it. The
is just typical acrylic paint. The air hose has a knob at the side
you connect to the can, I guess it works like a regulator ? But no
how I turn it, it makes no difference. The amount of the air seems to
the same.
I just want to know if the problem is at air source, the airbrush or
the paint.
Would I be OK if I use a compressor instead ? I don't have a real long
plan. I just want to touch up some of the old models I did. So I would
to avoid investing on a compressor as long as I can get the thing to
and finish up my job this round.

Have you thinned the paint? Straight-out-of-the-bottle paint is too thick to spray.

Probably incorrectly thinned paint.
No. You can blow air through the air passage. That does not mean that the paint passage is not clogged. Disassemble the nozzle, take a closer look and you will understand how it works, what flows where and why air can get through.
