Howdy,

FYI, floats are set to 3/16" (not sure if that affects mixture settings?).


According to the Green Book, the SU carbs are "relatively insensitive" to float position. BUT, the SU shop manual and "Tuning the SU carburetter" book both say that float level is very important to a proper mix. Which makes sense: the height of the fuel in the bowl IS the height of the fuel in the jet. If too high, too rich. If too low, too lean.

Phil's procedure is excellent. The only thing I do differently is to set the mechanical adjustments first. I also back the high idle screw completely out and disconnect the choke cable. Then after the carbs are tuned I adjust the chokes.
