Got it. I believe I understand the choke now - thank you.
Also agree that it’s a MK II - sorry I did not mean to cause confusion.
I’ll intend to upset around a 70 jet.
For the weeping (oil around the spark plug), should I be concerned there? Is there a need or way to fix that?
Also for the intake, how can I check if it’s 14mm? Can I just measure the opening there? Is there a method that doesn’t require dismounting the carb?
