Were they successfully used on a 292 already? If not, do you have the internal jetting data (venturi, aux venturi, emulsion tube, main jet, air corrector, idle jet, pump jet, pump spill, needle valve, etc.)?
Very expensive to "tune in".
Panic, they were intended for a 292 but the build was never started. I would probably assume they were in need of rebuilding. I have seen rebuild kits and the price didnt seem that bad.
