: I have leaks out of the top of my 40mm sidedrafts. One appears to be through the plate held byc a wingnut (covering the needle?) and the other through an adjustment screw. So I have two questions:

: 1) Where can I get rebuild kits
: 2) What is the best manual for working on Weber carbs

Rebuild kits are easy to get. The best source for weber parts I have found is in New York. Try, (not webercarburetor, make sure there's an "s". The other guys are OK too, but I haven't bought from them, so I can't vouch). They have a decent website, lots of parts, new carbs, etc. Claims to be the official importer into the US. Otherwise Top End Performance has a good supply, too.

The "Mickey Mouse Hat" (with the wingnut) covers the jets, which are meant to be replaced without dismantling the carbs. There's a cheap cardboard seal under it, make sure it's intact. The fuel line connections leak easily; the big hexagonal nut at the fuel line connection should be checked, perhaps removed/cleaned/retightened, as should the other big, hexagonal brass nuts that keep the filter screens in place. The covers can loosen up too a bit. It's hard to screw up these carbs unless you pull off the butterfly valves and remove the throttle shafts. Otherwise, complete dismantlement requires only about 15 mins. Be sure not to lose the little steel balls that sit under pointed, rectangular weights in recesses on the bottom of the bowl. You might not realize that they are there until you have all of the parts removed, then tip the carb upside down.

: TIA!
