Pete,
I have made a standard rebuild on my SU's, i.e. the rebuild kit form CVI (without re-bushing: valve, jets, gaskets & I bought 2 needles as well). Nice kit, all needed parts were there & it's been doing great for the past 1'500 miles. That's why I'm puzzled the problems arise now...
I have kept the old floats (with metal hinge), so no worries there. What is really strange is that both carbs leak. So if the floats are at fault, they would have gone bad both at the same time. Can you buy this? That's why I was thinking of the pump... Moreover, I already performed matt b's test (blowing through the valves with the lid upside down) & the valves seem perfectly tight...
Anyway, a good valve cleaning will do no harm.
Tonite is THE night: "bring the car back home" operation is scheduled for 6 pm till ??? I'll have a small fire ext with me. Will report to you tomorrow!
Cheers!
Séb
