Paul,
A faulty valve/camshaft timing is higly unlikely unless someone messed
up things really bad when the engine was build up.
-Is your distributor OK, i.e. do the weights move freely and are the
proper springs fitted?
-Are all vacu|m lines connected?
-Are the carbs in order, proper damping with ATF or very light oil,
correct springs, no worn butterfly spindles?
-Are the correct needles and jets fitted to the carbs?
-Did you fit new sparkplug leads?
-Is the wiring of the electronic ignition connected up the right way?
-Did you check the mixture using a Colortune?
-Did you balance the carbs?
Most likely the mixture is to lean due to a leak somewhere.
