I recently purchased a used OLDER Concept II Model C rower. I have just upgraded to the PM5 monitor with wires and new erg handle. Now I am noticing that the damper control switch doesn't allow me to change - it just falls down into the #1 position. I see nothing on line to see if I can fix without a part... so I assume that I need to purchase the damper replacement kit, has anyone ever had this problem?
Also is there anything else you think I might need to "spruce up" the old rower

I have straps, shock cord and now the damper replacement kit in my cart........
