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? |

I learned something. Thank you. My old IDFs from 80s had solid brass float needles and seats. When did they change to rubber tips? I see your point and I do agree rubber WILL harden with age. I’ll double down though. Personally I would still just try them without disassembly. Worst case you get a slight seepage past the needle, which runs up the bowl fuel level and it runs a bit rich. Other potential downside would be continual weepage past needle IF the fuel tank were higher than the carb resulting in gravity feed. This would lead to long term bowl flooding and continued fuel weeping into manifolds during storage which wouldn’t be cool: This isn’t possible in a 914 since tank is below carbs. |
