The cut-out plugs I refer to are attached. If you use the long plug in an LM carby (All PowerTorque engines), you'll experience issues with your carby and engine cut-out.
The PowerTorque engine was released in the '80s. It's had a few minor updates to different components since then, including to the carby, but all Victa 2-stroke mowers made since the mid-late '80s (I'm not certain of the exact year) when the PT's were released have used LM carburettors.
Unfortunately, from what I can see there has been a lot of incorrect labelling of posts, images, and videos, relating to the LM carby, calling it a G4. If anyone out there, like me, looked at some of that material when they first started working on mowers and had issues with the "correct" parts, it could be that the videos and websites were showing and advertising what to do with G4 carburettors and not LM carburettors.
Finally, people need to make sure they're installing the 2nd wire correctly. When installing the wire in the carby, there are 2 hard plastic holes in the carby body. the connector needs to thread through the rubber grommet, then the plastic of the body, then the plastic of the body again, and finally the tip should be visible poking out of the rubber grommet on the other side. If that's not installed correctly, it obviously won't function correctly.
As an example of how many people may get this wrong, here is a video from pushmowerrepair.com:
Here's a list of things this video got wrong (At a glance, there may be more):
It's an LM carburettor, not a G4
He's using a long cut-out plug, not a shot cut-out plug
He installs the 2nd cable from the wrong direction
Personally, I push the short cut-out plug into place so it's securely in the carburettor housing, then with a small amount of WD40 on the tip of the cut-out wire I push it through the cut-out plug. Once in and pressing against the plastic of the cam, I back it out just slightly. Install the dust boot, 2nd wire through the boot and body, out the boot, never had an issue
