The other alternative is to use thin brass shim stock instead ... both these
procedures are covered at length in the now out-of-print Fuel Injection book
published by Metric Mechanic, a BMW tuning firm in Kansas City, MO. I don't
know how difficult it is to find a copy these days (I've had mine since 1986
or so) but it's the only book I know that tells you how to work on Bosch CIS
systems without a lot of special tools ... unfortunately, it doesn't address
the later K-jet systems specifically but it's still invaluable in diagnosing
the basics. FWIW, it also covers the L-jet systems used on various Japanese
and German cars...
