Hey folks, little update on the wing I picked up with broken frame tube at center stand. Wanted to make sure it started and ran before I put any amount of time and money in it. The engine needed a starter and battery. Turned on the fuel and started cranking and it came to life without much problem only the carburetors are leaking fuel bad. I'm sure the float valves are stuck open but a notice a little 1/2 turn valve near the bowl drain screws. What is this valve? Looks like a tiny petcock valve and this is where the fuel is leaking from. Any insight on this is appreciated.
