G'day there I have a B & S on my newly acquired Rover Colt 8 The engine Model is 125602 0127 E1 050822 FB I understand that this may well not be the original engine My problem is the throttle spring is not correct I have tried some different springs, but none reduce the engine speed when I throttle off hopefully my two pictures load One shows the position where the spring is attached, the other with no spring Could I get help with the correct spring, where to get? (EBay No, etc ) Is this the correct position for the spring? Thank you in advance Dave
