It varies depending on the airbrush, what paint, what pressure, etc, etc. In theory, it should be instant (what I refer to as an airbrushes "response"). In reality, it rarely is, but as long as it's consistent you can work with it.
Reducing your paint a bit more, or running the air up a few PSI are probably the simplest possible fixes. Polishing the needle can help, too. If you want to get into airbrush modifications, you could try a shorter trigger, polishing the nozzle and air cap, even re-profiling the airbrush needle (if you try it, buy some extra needles. It will take a few tries to get right).
Oh, also straining your paint can make a big difference, too.

I'm using comart paint, with relatively low psi, around 5-15, is what i have played around with. But i think i might try reducing it a little with some distilled water. Also, my airbrush control needs to some, a lot , of work. What polish should i use and is there a lube or grease to use on the needle? Do you put it on the entire needle?
My paint as been bubbling up in my paint cup, anyone have any idea why?

Water in comart ok, with an iwata get superlube, bubbling paint in the cup is either a plugged nozzle or your air cap is not sealing properly.

Okay, thanks
Plugged nozzle or air cap....
How would one fix that, i am currently looking to even find what those are :shame:

If its a plugged or partially plugged nozzle, soak it in alcohol or some kind of cleaner. Do not dig at it with anything unless you want to buy a new nozzle. I its just the air cap, try tightening it, fingers only, i that doesnt work, take it off, look for the oring and put some chapstick on the threads .
I believe AndreZa posted a link to a vid by Kirk Lybecker recently, its a youtube vid, he does a complete breakdown and clean of an iwata hp-c or hp-cs in the vid. Either way its a great vid.

I mprobably calling it the wrong name. I thinking the piece that goes on over the nozzle, it directs the air out the front.

My HP-CH doesn't respond well at low PSI, I can't tell you what PSI I usually run at because I just use the MAC Valve. It will pull great detail even at hard surface at a reasonably high PSI(30-35). To help with response, when you seat the needle, make sure you are using very little pressure to do it. I always have to seat it a few times to where it responds the way I want.

I agree.. and with the .35 in the cs you do not need to reduce com-art.I shoot it thru a .23 no problem 25psi is a good place to start with a thin paint like com-art IMO The CS is very forgiving you just need to learn how to maintain it

Sevastra - considering the airbrush/ paint combination you're using i'd say it's because your tip isn't sealed in the head of your airbrush.
An air leak in the front end of the airbrush will generally be what causes bubbles in the cup. It would also explain why you need to pull back further before paint comes out as the air pressure is dropping.
The most common material i'll use to fix this is teflon tape (also known as plumbing tape). I quickly go over it in the maintenance video i did about 16 years ago, link below:

Basically you just need to cut a small slice of teflon tape to wrap around the thread of your tip, before it gets screwed onto the airbrush body. About 1.5 - 2 turns is all you need of the slither of teflon tape.
I've heard other people around here recommending beeswax also. Have not tried that, but it should work just as well? Otherwise your best option is to use a liquid plumbers sealant - it's harder to come by but will give you a better seal.
When you overcome the problem, if you could let people know how you fixed it in this thread for future reference would be greatly appreciated! cheers bud

I am still trouble shooting this. I took my brush apart, i watched airbrush tutors videos about applying the Teflon tape, i did so, xacto'd a tiny slice of it an wrapped it around the thread, and then i used 3 in 1 on all my threads and the spring trigger, and the needle since that did feel a little rough. I put it all back together and was so happy, " YEA! This is gonna work now, gonna be so cool!" I went to do some dots and lines...epic fail. About 5 minutes or maybe even less in, air bubbles in my paint cup and my lines are never consistent at all, they skip and are all sad and retarded. Sooner or later this will get figured out, haha * shakes fists in air*

It really doesn't sound like a trigger, or sealing issue. Next time it does this, stop and let off the air, then pull the chucking nit all the way back and hold it there, then push for air and blow it on a towel or paper. Really sounds like you have chunks in your paint, I get this at times, and his clears it. Try stealing an old pair of nylons from the woman( wife, whatever) and out a small piece over the opening in your paint, under the cap, so it will strain the paint. I have some older, like last year, spectratex , that does this. I have just been to lazy to find the old nylons in the house.

Also try this. Spray straight water, maybe even food coloring, if it won't spray these consistently. Then we can go from there.
