Re: Tuning Dual SUs

Hi Gavin,
         sure sounds like you have a float level problem.  Either the
needle valve is not always seating or perhaps you simply have too high
a fuel pressure.  The SU's like no more that 3psi in my experience.
Do you have a recirculating system?  A regulator?

Did you weaken or richen the RHS carb to get it to idle - this would
tell you whether you have too much or too little fuel in the float
chamber.
