Weber Cross Drilling size?

[AHM]

Hi All,

Having discovered that the cross drilling under the carb is blocked, I have taken out the lead plugs.

Before I dash in with a drill... What diameter are the ducts? What size lead shot do I need to get to plug them again?

3mm. long series drill required. Usual one to be blocked is the choke supply.
Melt a scrap piece of lead for plug.

Thanks.

It was the choke as you say - absolutely solid both sides. Easy to clear with a hand held drill bit. Unfortunately my smallest extra long drill is 3.2 so clearing the vertical duct was a little harder.
