The carb manifold is shown below. Interior just seems cluttered and different. The pulse port is totally in the head. The hangup on 180 head rotatation seem to be the difference in the head's ''mating lip' and the restriction tab in the case. I do not understand transfer port design but the case part seems identical. The coil mounts are longer than the posts cast on back of head. (also one of the posts is larger bore and unthreaded)

The Zenoah website, http://www.zenoah.net/products/hobby/hob_index.html , shows a rpm/torque curves for 3 g23 models. The LH verison is the lowest rated.

Who has carb 'twister' for G23? Are they add-on to existing manifold insulator spacer or a replacement twisted spacer? Don't want to get an add-on that won't fit this model spacer.
