Blobing?

While using it I started getting a couple odd things happening that I want to run by you folks who can tell me if it was me (and my "technique") or perhaps the paint possibly drying.  I can't quite remember it happening from the beginning (as I was playing around for at least an hour and a half) or only towards the end of the session.  Ok, first thing that was happening was I would depress the trigger to get the air flowing.  I would start to slide the trigger back to begin drawing paint.  I was trying for thin lines and dots, but when I would get the trigger back a little ways no paint would come out, or it would take a few seconds to finally start going.  Sometimes I would actually overcompensate thinking I was not pulling back far enough, but somtimes the paint was not going until the trigger was 1/3 or more of the way back.

If it wasn't happening at the start but began later in your painting session, I'd suspect that you're experiencing a phenomenon we have come to know as "tip drying". Basically what happens is that paint accumulates on the tip of the needle/nozzle and partially or completely blocks the paint flow. If it's a partial blockage, it means that you have to draw the needle back further before the paint starts to flow. When it does flow, you may experience an irregular or uneven paint flow, sometimes with uneven or insufficient paint atomisation - this may be evident as blotchiness or apparent spattering, rather than a fine, even spray pattern. The solution is to have a swab moistened with a suitable thinner handy and periodically wipe down the tip of your airbrush during your painting session. Tip drying seems to be more prevalent when using acrylic paints due to their faster drying, and can often be the result of insufficient thinning of your paint.

The second thing that was happening was, I would slide the trigger back forward to stop paint flow and then let it up to stop the air.  I would go ahead, set up to do another line or dot, and this time before the paint wold flow I got a small blot of "Blob" that would fly out (not to be disgusting, but perhaps it is best described as a booger being blown out before the mist would come).

Again, this is the likely result of paint accumulating on the tip/needle. Wipe it down periodically as described above. It's also a good practice to start your airflow (while the needle remains fully closed) with your airbrush pointed way from the surface you're painting and then bring it to where you want to paint before drawing back on the needle to start the paint flowing.

Thank you Phil_H, I will give that a try!  The Createx is inded an acrylic based paint, so I'll see if that fixes the issue.
