I have a couple questions on securing my carb to the sump on my O320.
What type of locknut or washer should I be using? The Lycoming manual shows a plain washer, nut and STD-1763 locknut (palnut).
Second question is what torque should I use on the four carb nuts?
I found an old thread for an O360 using the following. Is this accurate?
AE9887-5 4 Nut, Hex, Lock, 5/16-18 UNC 204 in.-lbs.
AE51412-5 4 Washer, Plain, 5/16 ID
AE51413-5 4 Washer, Internal Star, 5/16 ID
