OOOPs sorry, I misunderstood the question. I just crank mine, till I get fuel to just drip out the nozzels at WOT, close the butterflys, flip on the magneto, and it fires right up. Be sure you have the leakdown on the barrel valve set, and you shouldn't have too much trouble. W.J., all the stacks I've ever seen, didn't have a distribution block, the nozzel hoses, come from the barrel valve to the nozzels. That's not to say that they're isn't one with a dist.block, I've just never seen one like on an Enderle.
Good luck qiksix
