I have a refillable aeresol can from HF that I can fill with lacquer thinner and spray the torch tip parts and maybe un stick them.

I'm disassembling some tube type wrought iron fence to build up some stock but it also gives me practice in cutting thin stuff and tack welds without going thru...well most of the time.

I have a bunch of 3/16" X 2" angle iron brackets I have to disassemble, too.

Gotta make this plasma cutter pay for itself.
That delay indicates a sticky piston binding, you could pump it up and down a dozen times to break it in or clear it, the other possiblity that comes to mind is the trigger switch is not making a positive contact, it's a very simple switch, the sticky piston is my first guess, make sure the consumable is tight.

I don't think it is a serious problem just painful one, keeping your air dry & clean is important
