First thing I’d look at is if the piston is sticking. Unscrew the damper and then lift the piston with your finger and let it fall. If there isn’t a metallic thud as the piston closes, well there should be. Most likely then is the jet isn’t centred properly. An internet search will tell you how to put it right.
