Yup, the fuel is probably leaking from the cold start units. I've sealed mine off with an internal plugs in place of the pistons and the blanking plates. There is no more fuel residue anywhere on the outside surfaces to show otherwise.

These folks are the main source for Weber related stuff in the UK. The plugs I made myself. They'll have the blanking plates though.

Now that I've got those cold start passages air/fuel-tight my mixture settings have changed noticably. Now have some slight popping on overuns that was not there before. Have to use my AFM and tweak the jetting again.
