Balancing Carbs - Where are the adjustment screws?!

[Dead Eye]

They are a pain in the ass to locate and a small torch will make your life easier... the screws are hidden in between the carbs, which you probably already know

I usually unbolt the rail holding the fuel pump and coils as it does make access a little easier - I think I removed the coils from the rail at one point but I don't remember if that was for balancing or not...
