RE: Thunder tiger pro .46 loses power
The fact that the nipple is falling out is a perfect example of poor quality control. You will never see that on an OS or Enya engine unless someone took it apart and didn't tighten it well enough. Adjustable?? I don't think that is the word as it's not adjustable any more than head bolts or back cover bolts are adjustable. Needle valves and valves are adjustable.
