Next installment.....
Decided to go ahead and get the cable replaced as we're pretty well convinced it's that that's causing the pushbuttons to stick. There's only about 1/2" gap in a couple of places as it runs down next to the exhaust & 'header' flange.
Options are to get one from Imperial Services in the US, who may be able to make one a bit longer so we can re-route it to avoid the exhaust, or to use Speedy Cables (now in Swansea) who will definitely be able to supply a longer version and may even be able to re-use the ends of our cable.
We'll give Speedy a ring first as we've heard good reports on them
http://www.speedycables.co.uk/ and they may even be cheaper
We used a bit of pneumatic pipe to work out a better route for the new cable (the green stuff in the pics). We reckon 8 inches longer should do it
Once off, and with the heat-refelective material removed, we could see the cable had been burned thru at some point, prob before the wrap was put on tho

Dunno how much damage internally, but it was pretty damn hard to move the inner without a lot of force.
So we'll have to wait n see what Speedy Cables can do. Let's hope they live up to their name.
Other little prob is getting the bracket off that attaches it to the pushbutton unit. It's been bent over (to retain the cable) so much over the years, it will more than likely break off if we force it open (last pic).
We'll measure the old one so we can get a new one fabricated if needed
