Zenoah, all engines.

The new 240 and 270 only.

230 (231 for the marine engine) and 260 have different bores.

240 and 270 (car engines) are updated, main difference is a 4 bolt cylinder (as in the marine and helo engine) instead of 2 and an additional bearing on the PTO(as in the helo engine) still 22,5 and 25,4cc.
