I just recently bought a 1973 MGBGT in need of much
restoration and attention.
On driving it home (it runs!) my wife was following and
noticed a fair amount of black smoke from the exhaust
when I accelerated. I immediately thought oH no not the
piston rings etc.
Anyway a bit of background this car has been sitting for
about 2-3 years, the previous owner claimed he started it
up every two months or so. The oil looks pretty dirty,
the car seems to run ok. the plugs are black.
I checked the compression 'dry' last night, but the engine
was cold. I got 120, 105, 110, 115 psi, which is not great,
but is this bad enough to cause the smoking, or are the carbs
just set too rich. Obviously I need to put in fresh oil etc. before
I consider further driving etc..
Which direction should I be directing my efforts. I really don't
want to have major engine work, (obviuosly) - partly because
this is the first MG I have come across that doesn't leave
oil drips on the garage floor (yes there is oil in it)
Thanks again for any comments.
