What is the hole that isn't the pilot jet or main? At 4 o clock to the pilot in the picture?

I'm on a strip down/clean everything again routine and would like to knowwhat it is, no mention in Haynes etc

Yep phil x is onto it. I cleared that through with a piece of fine wire and it finally meant i had a functioning choke.

Do you want me to clean your carbs?

Contact me if you want me to come over and pick them up.
