Hi Mariano,

Good that it is heavy. Sometimes those springs are broken or weakened and as they are not a standard item they are difficult to replace. Other methods of a pedal return spring have to be set up.

Perhaps if you lubricate all the ball linkages with something like white lithium grease it may help. Don't forget the grease fitting on that linkage shaft on the front engine cover plate on left side.

Cheers.
