"Small diameter lines would point to primer lines or recirculation lines. Re-circ lines come out of fittings in the crankcase behind the carbs. The routing differs between models/years, but most end up at a fitting on the side of the crankcase or on a bypass cover. Primer lines attach near each carb and go to the primer solinoid valve usually located on the air silencer."
