I went ahead and swapped the diaphram/piston/needle assembly from one carb to
another. The gunsens shows the mixture much more consistent throughout the
RPM range. Now the only problem is the new piston shaft seal seems to be
leaking the oil out of the dashpot. I know the fix was described before but
does anyone know the size O-rings I need to make the repair?
BTW the original diaphragm was in good shape, no leaks that I could find, I
think a PO must have done something with the needle.
Also has anyone retrofitted the older style adjustable jet set into a newer
carb?
I'd like to have a vernier adjust for the mixture that I could adjust from
the cockpit, use a EGT gauge to make fine adjustments to compensate for
altitude and humidity.
