Carburetter vent hole

[936cbpminor]

In the September/October Minor Matters there was an article on the vent in the top of the carb float chamber. I have looked really closely on mine and cannot find ANY evidence of one. Where should I be looking or are there different types. Cannot belive it is so corroded up that it is invisible. Symptoms are similar to that that was published.

If you remove the petrol pipe tube from the carb there is a plate in front of it which covers the hole, this just pulls off revealing the vent hole.

Thanks Trickydicky. I actually removed the fuel pipe and the hole is underneath the hose!
Quite large at aout 1/16" and not blocked. The article, as read, implied a hole in the top by the words Birmingham. Mystery now solved.
