That was exactly what i had in mind, very crude
Get that bleed valve off if its a bailey twin piston then it shouldn't be there, and it will contribute to some very poor idling problems among others.
It idles perfectly ok, albeit at just over 1000rpm. I'll remove it at the w'end to see if it improves the other no-go / go problem.
