What a blessing!
Saturday, I removed the air filter from my mostly original 1986 F150 with 4.9L, to adjust the idle speed. After disconnecting the cold-air duct and hoses, I carefully lifted the entire filter housing and set it aside. When I returned, I looked at the top of the Carter YF carburetor [Duraspark 2 conversion] and noticed that the "bridge" which the wingnut screws into to anchor the filter, was loose on one end with the screw and lock washer missing. GULP!
I had not heard any metallic sounds and the engine was running well, except for a low idle speed due to a timing adjustment.
I then went to the filter and removed the top, exposing the element. There next to the opening which rests on the top of the carburetor was the lock washer, but NO screw!!! After thinking for a moment, I went to my tool box and got a magnetic wand and placed it in the carburetor and wiggled it... I heard a "ting" and the screw was retreived.
This was a rebuilt carburetor, two years ago, and apparantly, this had been a problem as the screws are longer than normal, perhaps to reach undamaged threads. Any ideas about securing the screw? I am thinking "loctite red".
