I have a 3678-12 (-12 runs a tad richer than the -32 but otherwise almost identical) It was rebuilt before installing in my O-320 2 years ago. Jet is the upgraded pepperbox jet (for better atomization) and is drilled for the 320 in the RV. It worked very well on my engine for 80 hours and then I upgraded to an FI setup.
PM me if interested.
RV-6A / IO-320, Flying as of 8/2015
