I have a Marzocchi MZ 1 fork on my bike. I got it used so I'm not sure how it is supposed to function in the pristine condition, but according to internet search the lockout knob also functions as a compression damper knob. Well, the lockout works fine, but out of 10 clicks of the lockout adjuster knob, only 2 clicks seem to have any effect on the compression and they feel like the fork is "half locked out". The manual warns that the fork should not take any big hits when the fork is locked out, as it could blow the damper cartridge. So, I am worried that I could damage the fork if I use the "half locked out" settings, which are just 1 or 2 clicks from full lockout. As a result, I usually put it it somewhere at position 4 (between 0 and 10) but it feels a little too springy. AFAIK the damper unit is a sealed oil cartridge...is there anything I can do to restore its compression damping?
