Monobloc 389 376 floats...
Are they both the same? interchangeable between the two carbs? I'd have thought so, but one plastic float that I have is marked 376. My other spare floats are brass with no identification on them, so I don't know if they are from a 376 or 389 carb they look the same though. I've removed a good working 376 carb to put on a 389 one and I'm finding that ticking the carb takes quite a few moments for the fuel to come up to level. Running tick over seems ok.
