It will set the car on fire very soon.
The plastic tube isn't suitable for a brass olive at all as the olive will never clamp around as it's not a solid metal material. A few times choke on and off will have the tube pop out of the chamber.

Ah yes, but you're forgetting the flanged brass insert in the end of the plastic tube to the jet. That insert is what the rubber seal is normally squashing the tube onto as it's compressed by the gland nut and the flat washer behind the rubber. Otherwise, that rubber seal would equally never hold just the plastic pipe in place. And the thinnest part of that end of the olive is crimping to trap the end of the tube between it and the flange, just as the rubber would. And, as the sharp end of the olive should "dig in" to the tube, it should pull out even less easily than with the rubber.
I fitted one of the old jets to a spare chamber using an olive, and I couldn't pull it out with a fair bit of tension on the tube. I can't say the tube would have torn first, but it felt pretty solid in the hole. So I ain't overly worried.
And I don't see that there's a lot of tensional stress on the tube as the jet is moved up and down by the choke anyway - the outer spring on the tube will always be trying to keep the tube straight and should ensure it's always pushing into the chamber orifice whether the jet is up or down, and also when it's neither up nor down.
But, given your obvious and touching concern for my safety, I will look at putting something between the front carb and the alternator to deflect any drips. I admit, at this stage, I'm thinking about bacofoil and tiewraps, though.
As a matter of interest, the AUD 545's don't have an overflow pipe on the float chamber tops - at least mine didn't. So, if the float needle wore or jammed, like they do, the front carb would have overflowed straight onto the alternator. I have swapped them for lids from some 663s off a later Sprint and fitted the green plastic tubes. But did that many of the first batch Sprints spontaneously combust?
