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 haven't ever converted them to disabled as they already had them and I didn't hook to a cable or they had block off plates, but I believe there is a kit that removes everything in the cold start system and gives you the block off plates to close them up so you shouldn't need to bother with finding that washer.

I already have the kit. It is just a block off plate that removes the lever mechanism but you do have to keep all the guts in place to make it work. However, there is a lot of info here and on the Webs about how the little pistons in the cold start mechanism can get stuck in the open position which will make the engine run very rich and could scour the cylinders. What I was attempting was to follow Perry's procedure (see link a few posts up) to tap the bores and insert a brass set screw that holds that piston down so it can't migrate up and get stuck. As long as that piston remains seized in the bore like it is now, there will be no problem, but I'd like to have some assurance it can't work loose so I need to put something in there. Here's another thread on The Samba of someone using brass rod but I think they are still holding it in with the washer. |
