Used my Rover walking frame yesterday, and found it only had one speed, regardless of throttle setting.
Pulled the plastic throttle apart, not there ........... must be jammed somewhere in the cable, not there ............. carby linkages, they slide, but not as much as they should, why ?
Must have smashed it against a low bush branch, and bent a linkage just enough to stop it sliding as per the manufacturer intended.
A tweak with the pliers, and a major dilemma averted.
Had to have a cup of coffee and a nanna nap after all that.
