Hi oztayls,
Nice little write-up there, good stuff.
Personally, I've never really had an issue with the carby and the cut-off switch. I don't really understand all of the issues people have with them and the cut-off. I know that lots of people have written on here extensively about mods you can do to them and alt. cut-off methods, I just don't get it, probably because I've never experienced it myself.
One thing I would say which is something that threw me off years ago, make sure that when you install the cut-off plug into the carby (The one that goes into the body, not the one that slides through the outside), make sure you use the plug grommet, not the one which covers the whole electrical connection and goes into the carby. The long type plug isn't designed for the LM carby, the short, plug-type is designed for the LM. Using the wrong plug will cause the cam to jam on the throttle and that could be causing you issues. If you use the long-type and as such the connector doesn't go into the carby far enough, you could end up with a cable with too much wobble/play on the outer side, meaning it might connect with the cut-off cable when you don't want it to.
Also, I believe the carby in question here is an LM carby, if I'm not mistaken. The LM carby replaced the G4, and the G4 was never available on the PowerTorque engine. From what I can see looking around, a lot of people make this mistake (Unless I'm the one who got it wrong for all of these years haha).
