Design Improvements for the Zenith 601 HDS: Linkage for Carburetors

Linkage for Carburetors

The standard cable system of the carburetors seems quite unsatisfactory. Getting and keeping the carburetors synchronized is difficult. Also, if one of the two cables fails, one half of the engine goes to full power. We do not want to be there when that happens. Instead, a rod system is used that assures positive control of the throttles. The rods are easy to make and install, and they require no maintenance or adjustment except for an occasional drop of oil for the rod ends.
