I just got my TC-20 last week and have been trying it out this weekend. I'm having an issue with the regulator not adjusting very well. I can turn it 2 to 3 FULL turns and the needle will not move. Then a little more turning and it jumps 10 psi at a time. It seems to go from 10, 20 or 30psi only. can't getting any smaller adjustments. Lets say im at 10 psi and I want 15, I'm having to turn it A LOT just to get it to go five and then it will jump over 20 sometimes. Anyone else have this issue that owns a TC-20? I'm not sure if it's just a cheap regulator or broken.
