Got at it noonish. NO such luck. Tried both points devices with no sparks. I'm about to return the Dynamator to the engine where the regulator wiring is built-in. It was a lot of fingering. Today was the USMC 250th Birthday. I missed out. Early morning start. Still have until Friday night.

Exactly. 😄😄.

With that much petrol vapour around, it might take care of itself.

Thanks Ray, that makes perfect sense. I forgot that the bolt remains stationary while only the nut turns.

That's exactly what mine are Guy. Double wire band. The original ones on the car.

I think if I kept screwing it tighter, the clamping force is so great, I'd either strip the thread or cut right through the rubber.

I've even tried using petrol resistant pu sealant under the neck ends. No difference.

It's impossible to pin point where in my boot the smell originates.

Your spring clip solution looks a good idea for when the glass is removed.

You can`t see it but the XPEG rod is substantially
meatier than the XPAG. You can also see the difference in the cap bolt heads.
As I said earlier, the only reason I can think of is to change the the top piston rings. The 72mm piston will not pass down past the crank like the standard bore XPAG.

I cut a spring steel fixing as shown. I then ground the centre web out on each side of the old screw hole.
The cut part of the spring steel clip is retained in place by the windscreen seal, although you could put a drop of super glue to retain it. Don't forget to cut the point off the stainless steel self tapper. Points and glass don't get on together.

This is the view from the inside of the frame which shows just how little alluminium there is to retain the screw thread.
See next comment to see how I fixed the problem.

the head of the bolt has a flat machined on it, The flat rests against a flat on the con rad preventing it from turning when tightened. It allows the bolt to be very close to the journal without weakening the big end eye.
The 1500 has another flat to clear the bore (I think)
does that explain it OK
