I didn't want to hijack the other thread but have a question about my own Webers. They are Italian 40IDFs I bought in the late 80s or early 90s. Other than finger tight bolting them on to my engine to see how cool they looked, they have never been used. No fuel has touched them. I don't remember if I even opened them to set the float levels. BUT... they were stored in a humid basement for several years before I moved to a civilized climate. So, the magnesium housing is tarnished on the outside and the plating has deteriorated on a few of the levers and such. Pretty minor stuff from what I can see.
My question: is there is anything special I should do or check other than inspecting for corroded parts and normal setup as I prep these for service? |

What elevation you at? (My jetting is a few hundred above feet sea level)
Engine size? The distributor in the pic appears to have too much play at the end of the shaft. Shim it. When setting the AFR screws start approximately 3-4 turns from lightly seated position. As for the idle speed 1/2 turn in from first contact of the lever. Any further in and the throttle plates will begin to expose the progression circuits. Float height needs to be 10mm - 11.5mm with the gasket in place ball NOT depressed. Float drop (not as critical) 28-32mm Fuel pressure 3-3.5lbs max |
