i just set up my brakes and steering clutch linkage as best i could as per manual. the brake bands needed a lot of titening to adjust up. so after trying it a little it seems much better, at least now foot brakes work and steering levers dont need to move as far as before. i tried forward in all gears. all good. now in reverse it wants to kill the motor upon realising the foot clutch so i was carfull not to fully realeas the foot pedal. i tried it again realeasing both steering clutch levers, and let out foot clutch. that was good, no killing the motor. then upon realesing slowly one steering clutch lever, and it tried to turn the track in reverse. tried the other side and it wants to kill the motor? any ideas what the problem mite be?
