Hi Rich,
With roadsters (and in general with any car thinking of Murphy's Law) don't
assume anything! You find a problem, fix it and see if you get good
results. And then go looking for something else to fix!
When you turn the float chamber cover upside down, and using a ruler, measure
the clearance from the cover to where the lever contacts the float. I think it's
about 9/16 inch (check a manual to be sure).
The best way to deal with a carb problem, is to check as much as you can while
you're at it. That means testing the floats for leaks, checking the fuel inlet
lines for blockages (there's a small filter trap in the fuel inlets). Check the
fuel outlet and jet needle nozzle for blockages and dirt. While you're at it,
lift the suction piston and drop it, testing for a smooth drop and no hanging up
of the jet needle into the nozzle. I know it sounds complicated, but once you
carefully take apart an SU carb you'll see it's not that hard to maintain them.
Just be careful with the piston and needle assembly, you don't want to bend or
break that needle. Some people say they're hard to align, but I haven't had any
problems. Alignment problems could be due to bent needles. If yours is bent,
better to find out now so you can get replacement needles and nozzles. Also,
invest in a UniSyn carb balancer, worth every penny it costs.

Hello,
I own a 1970 1600, and I have a question regarding the float valve lever
in the float chamber of the carburetor. My car was sort of sputtering when
I depress the gas pedal. I adjusted the timing but didn't get rid of the
problem. I then figured the problem must lie in the carburetors so I
disassembled the float chambers and happened to notice that the two float
levers are not the same. Should they be the same? If not can I assume
that one is broken and could this be the cause of the sputtering? Thanks
for any information or advice.
Rich
