Zenoah ZG 23/26 Cast Aluminum Intake Bend
In order to obtain a quiet engine you must not forget to do something to reduce the considerable intake noise. For model aircraft the simplest and most effective method is to draw the intake air from inside the fuselage. To fit the carburettor to this bend, the fuel nipple on the ZG 23SL must be turned in the carburettor body. This nipple consists of a brass core with a riffled edge over which a plastic spout is injection moulded. If you try to turn this nipple with pliers, the plastic is forced to expand over the riffles, making the nipple useless as it will only leak.
Plug and play on the ZG26, some modification needed on the ZG23 to make the fuel adapter line up.
It is strongly recommended that the small intake tube be used.
