Thanks James.

Well I managed to test the mustang today and I can confirm it is a first pull starter. It idles pretty nice and full throttle sounds sweet.

I have one problem I cant get the damm thing to stop without turning the fuel off.

I replaced the carby connector arm thinking it might be faulty however the same problem still happens. I took the carby arm connector off and tried to earth the engine on the body as suggested by Gizmo and Bigted but still no go.

I would appreciate some assistance.

Thank you
