I have converted a OMS hill climb car to FB. It has push rod front suspension and pull rod rear suspension. It came with AVO adjustable shocks. They have a dial that is adjustable at the bottom of the shock body centered in the shock. I think memory recalls maybe 5 or 6 settings. I have tried adjusting them making large changes at the track and haven't noticed much change to the handling of the car. I'm questioning whether they are even functional. A simple push/pull test by hand only reveals resistance. In other words they don't appear to be totally dead. Anybody know who may be familiar or work with AVO shocks? Thanks in advance.
