How Hard is DIY Valve Adjustment?
 

Once again, this is a 1995 Civic EX 1.6L 125HP sedan. Don't have the
serial number at hand. I've done valve lash adjustments on old Volvo
pushrod engines, but nothing like this. It sounds like the adjustment
mechanism is surprisingly similar, though: set screw and locknut. So,
any tricks? Is this something best left to a seasoned mechanic? I have
the Chilton manual.
