Walbro carb on ZDZ 80B2-L
Hi.
I have a ZDZ 80B2 engine with a Walbro Carb on it, and I think something is missing on it. Below the two needles there is a threaded hole with nothing in it, and this hole has another hole 90 deg. to it with a small spring and a screw in it.
I wonder if anyone know off the top of their heads what this hole is for, and what is supposed to be in it? Or do you know where I can get a exploded view of the carb??
Any info will be appreciated.
Happy flying
