things to look at...
coil breaking down,
fuel pressure, lucas fule pump
air/vacuum leaks
cracked distcap/rotor, leaking plugh wires[ high tension leads] fouled
plugs
to thick/or no oil in carb slides
one carb float hung...etc
carb linkage
pvc diaphram...althought this should cause smoking[ as in oil burning ],
on top of the intake manifold between the carbs...remove the metal keepr
spring wire, prise up the cover remove and clean the rubber, hold up to
a bright light and look for daykight , daylight = replacement
since you mentioned having to set timing freguently , recently, have you
checked the points...the fibre tab that rubs the cam , can wear , and
faster with out the dab of grease it shold have,,,[if you running stock
ignition]
brit cars will make you a deep thinker...so will italian, german, etc
