At last! a far more prosperous day.
Got the throttle cable removed and took it back with me as a sample, then another job which has been halting progress, unfortunately this machine is in such a state that everything you touch turns to salvage or a pile of rust in your hands. One such item was the exhaust heat shield that was fitted to the exhaust manifold to try and stop heat from getting to the rocker cover.
I had already decided the best way forward with the heat shield was to fabricate one out of stainless steel, saves much aggro, yesterday I popped into a local company who are very reasonable and they cut me off a piece of stainless plate to shape. Today all I had to do was bend it, drill it and fit it, all easier said than done, the main issue was the 1/4" bolt that held it in position had snapped off in the manifold which is too tough to tap, so I carefully drilled the 1/4" bolt dead centrally then tapped it M5 a good result
the other hole is for location so I drilled that and fitted a scroll pin, job done.
Before the manifold is refitted there is one more job and that is to remove the rocker cover, there are some issues with that
once that's done hopefully start some reassembly. With the heat shield done my attention turned to the throttle quadrant which I removed all the rust from, freed up and painted, so all in all not a bad day despite the heat.
