Trevor/Colin,
Thanks for your views on this one. I know the " Solid vs. Composite " discussion has run and run on this site, and I think I have read most of it. Yes, I did the gradual torqueing down, but the gasket was from an old set, and was obviously past its best. I should have bought new, but got caught in the adrenalin rush of : " Summer's coming, must get it finished.......". I don't normally skimp on parts, so don't know why I did this time. Another lesson learnt, then.
Incidentally, when I finished the A10, I had the same problem, but sorted with a solid gasket. 1200 miles like yourself now with no problems.
Thanks Wardleybob for your advice. I did have a problem with the Amal at first, where the new Viton tipped float needle was sticking up in the seat, rather than falling out, but another needle seemed to work, after I did the old
' clingfilm over the float chamber ' trick, as suggested by somebody on this Forum, so that I could see what was going wrong. A good wheeze, that.......I would probably never have discovered why I was suffering from fuel starvation otherwise !
Take care, and don't get carried away in the good weather UK riders..... I had a narrow escape yesterday going into a country lane right-hander about 10 mph too fast.
