DasBeav,
I have the same airbrush. Love it, but it takes a lot of cleaning to get it to run smooth. It took me about a year to get the cleaning down to about 15 minutes and getting back in service. It is easy to break down and get all the small parts clean. I bent my needle too and noticed it really messed up my flow, paint dried to the bent part and spackled really bad. I thought my nozzle cap needed to be replaced too, but after replacing the part, it didnt change anything. It was all needle. Back up and running and it works like new. I recommend full break down and cleaning after about 10 uses. I put a dab of petroleum jelly on the spring from the air inlet housing and a tiny bit on the needle, about the center of the housing, keeps the trigger control smooth.
Hope this helps.
