I have a Graco 3 stage HVLP. Love it for shellac, lacquer, poly, dye,
etc. I bought a bigger tip. I have a 2qt pot that takes pressure from
my compressor then a material line out to a gun which has the hvlp air
also. It blew the BIN primer well but the Latex\Enamel Semi Gloss was
almost to heavy to spray but I got a decent spray after tweaking the
flow\air\etc.

I am getting small air bubbles in the paint. Just pin head sized but
lots of them they don't pop and end up leaving nibs once dry.

I know this setup is barely strong enough to blow latex but wondering
if anyone has any ideas. I did use some flowtrol. Not sure if that was
the issue or if I should use more or what.

I am pretty sure I had the gun and lines clear of the alcohol from
cleaning the bin and I sprayed one side of 6 cabinet doors and was
still getting bubbles although tweaking to lees paint seemed to help a
bit.

I have sprayed, supervised spraying and problem solved spraying issues
for decades.
Not always successful but somewhat educated I suggest that latex, when
sprayed, should have a serious whack of power behind it and that
spells: airless. Flowtrol is your friend, so is a bit of water.
Temperature and humidity are huge factors as well.
I seldom comment on spraying techniques as there are so many variables
that will/can drive you nuts.

Think about it... that stuff is rubbery (In the UK they call it
emulsion) so to atomize it requires power.
Yes it can be sprayed successfully, I have on many occasions, but you
need to stop thinking that **** as being paint. The 'aint' component
of the word sums it up.
