Emmision Controls

["Eric Storey" <eric_storey@mail.mba.wfu.edu>]

I am looking into buying an MGB to restore.  I know that emission controls
first appeared on the 1968 models.  My question is when do the emission
controls become so complicated that a nonprofessional might have trouble
working on the engine.  I think 1975 and later models had catalytic
converters as well as other emission and ignition controls.  Are 1968-74
models relatively easy to tune, etc.?
