Webers should stop leaking now.

No matter how many times my mechanic tried to stop the Webers leaking from the bottom bowls they just kept leaking. So while the distributor is away for a rebuild I removed the Webers purchased some new, longer stainless screws (he replaced the originals with shorter black screws) and put it all back together using a small film of Locktite 518 sealant. Hopefully this will stop the leaks.
