Throttle control B18A Duett Ch 83400-

Sluggish throttle response, play in the linkage or a throttle arm that doesn't return evenly can often point to worn ball joints and dried-out bushings in the throttle control. On the 445 with the B18A from chassis 83400, the force travels from the pedal through a series of levers and joints to the carburetor, and every worn joint adds dead travel that's noticeable when you open the throttle.
