Spent the morning sorting out carb bits, cleaning them out and making a 'bitsa' carb with my spare body and my existing float bowl. Fitted new throttle spindle, a decent butterfly and a new needle valve (with the thickest washer of the three that Burlen sent) and cleaned everything out with carb cleaner.
SUCCESS!!!! I now have a carb that works as I would like. The tickover is about half what it was (circa 500 rpm by my estimation) and is nice an even. Took the car over the mountains to feed the horses and visit a friend at Llanrhaeadr-ym-Mochnant so did about 40 miles with no problems.
Still don't understand what is the matter with the other carb body, though.
As requested by Ruairidh, I post photos as follows:
1. Top of the carb (my spare body) numbered 26VA C (or 0) 548
2. Top of the old body (the one that was giving me problems) numbered 26VA R1634
3. Bottom of the float bowl I am using that was originally fitted to R1634 and is now on C (or 0) 548
4. Bottom of my spare bowl (which when fitted to C (or 0) 548 hunted badly and was quickly replaced by my original bowl.
5. Generic shot of 'bitsa' carb in place.
Any ideas as to what is wrong with the R1634 carb body would be most appreciated.
