Slow progress, I've got the replacement oil pressure switch, cleaned up the oil cooler adaptor, and repositioned as recommended in a CVH tuning manual. Gave the oil cooler a good flushing, plenty of black treacle :-).
While removing the carbs, 2 of the studs came out rather than nuts coming off. So suspicious of threads. On close inspection, UNF portion of most studs have a damaged thread, and the MISAB 'O' ring mounting plates are all perished, so no wonder the carburation varies. :-(. So more parts on order, and hopefully can put it back together, and will run better.
Also took the opportunity to do some cleaning around the engine bay. Plenty of parafin, and rags, just no source of ignition please !

Exhausting Concerns
After visiting Doune at the weekend, and realising why it;s referred to a car eating course. Saw 3 crashes including Roger Moran in his Gould.
Needed to Get back to my car, sorted the steering rack, with a new set of gaiters, and not as difficult as feared, as the car hasn't been subjected to road salt, muck etc which normal road cars have to suffer. So thought a bout a 'quick oil & filter change'. This proved to be a marathon, could not get filter to rotate, tried using a ring compressor, with no joy, then a screw driver punctured through, still no movement, but was limited as this is below the twin 45's. So, off came the carbs, tried all sorts, ending up with a piece of steel pipe over a screwdriver correctly aligned, eventually got some movement !. However, in the process smashed the top off the oil pressure switch.:-(
Anyway, allowed me to check the oil cooler adaptor, clean & reposition, and then decide a good flushing of the oil system is required.
While reading the MAS 'Blue Book', I found the regs about exhaust placement. Problem with interpreting what it should be. Not sure if it's not supposed to protrude beyond a line between the front & rear wheel, or if a 40mm protrusion is allowed. It appears to be right on the 40mm protrusion, otherwise, its a bit of surgery !
What seemed an easy project is now getting protracted.

We have lift off
Now with the trailer allowing mobility, got the car to a local rolling road (1/2 mile) to get the carbs/ignition checked setup. The owner of the rolling road etc is Bob Henderson (Argyll GT Turbo, Minnow Fish carbs), who is very knowledgeable. Plenty of history racing, building racing engines for the big boys etc. Anyway, after various problems, got the carbs sorted, but had difficulty holding the car on the rollers, as there's not an easy way to load the rear end as most is fibreglass. Bob is cheap - £45 to get sorted !
As the car was running better, I thought I'd take it for a run up the track by the house, which has been graded that day. Car went great, up into 2nd, BUT created huge dust cloud, which didn't impress the golfers !
However, it did allow me to find out that the steering was stiff, just not slow speed heavy.
So opened up the rack to check for lubrication. None showing, so started filling, and then went in for dinner.
Came out to find a puddle of gear oil !, the gaiters had perished. eBay to the rescue for Vauxhal Fireza gaiters.
Also found a fuel leak, thought must be one somewhere, as there was always a 'petrol' smell, and the contents of the fuel tank was disappearing faster then expected, even with the small tank !
So, a rack overhaul in prospect, and sort out fuel leak. Oh, what fun
