Been working way too much, so even though I bolted the q-jet back on weeks ago I didn't get time in to troubleshoot what wasn't working. Bowl wasn't filling, needle valve is stuck closed.
Beast runs fine when the bowl is primed, but shortly leans out and dies. Cracked the filter housing and fuel got that far, so clearly the pump was working, vacuum tested from the filter housing and it proved the valve was closed. Triple T technology (tap-tap-tap) had no effect. Tried with a little air pressure instead, no joy.
I had bench tested this with vacuum (upside down)when I put the valve in the seat after rebushing the throttle rods, but something must have bound up in final assembly.
Gotta pop off the air horn again. This time for sure
