more progress and another question 444-544

Sil, did your 122s have SUs? Yes. Same setup, but without the fancy air cleaners, of course. ;-)

BTW, I didn't mean to imply that heat from the exhaust manifold should be ruled out, just that, based on my experience in a very hot climate, I'd check out any other possibilities first. On the other hand, wrapping something non-flammable around the floatbowl and lower jet doesn't involve a lot of work, and if that does the trick, I'd be delighted to have been wrong. Should your plugs, by any chance, show evidence of leanness, rather than richness, it could be that the exhaust manifold is getting bit hotter than it should, at least, so I've been told - no personal experience. I believe that retarded timing can also overheat the exhaust.
