Me and Jet Mech attempted to take the gas block off and we had problems with the 1 dowel pin located my the detent pin. IT WAS IMPOSSIBLE, so I took it home.. Not satisfied. Decided to buy a BFH and give it a go. 3 punch pins later (1 being jet mechs) , it decided to budge, After it broke off the length of the 1/16 punch pin, I had maybe a 1/8th of a inch left. Just enough to give it a good wack and make it budge a little. Shaved down a 1/8th punch pin to about .100-105 and couple a could solid wacks from this mini sledge and boom, popped off. Whats weird is detent pin and spring did not move?
