OK I did some looking at the replacement big block cylinder kits and found "They" only have two mounting holes for the cylinder. The Zenoah G23 and G26 "RC" versions have four (like my G23 and Kalt 22). Ralph, if you're listening, will any of these kits fit the "RC" versions using only the two cylinder mounting bolts? I'm trying to justify replacing the cylinder on the Kalt (not in great shape) and this looked like a way to go as well as up the hp. Was also looking at having one of your ignitions put on it.
