Morning Gang!
I had a good weekend with the '70 B-GT:
+ Got the fuel problem sorted out. Turned out
to be a clogged fuel filter after all. It didn't take
too long to sort out. All flows well now.
+ Masked and painted the engine compartment /
grill area ahead of the radiator, reinstalled the
wiring harness, repainted the grill matte black,
installed a new 'MG' badge, cleaned and polished
the Al trim strips and drooled over the beauty of
it all -- just a bit.
+ Couldn't resist it so I put the car in gear and
rolled it forward a couple of feet, then back
again all under it's own power. I know that this
is silly but there is just a romance associated with
moving the car under it's own power for the first
time after a rebuild. It was private and it was
rewarding. No one outside of the motorhead
community would understand -- but you do. :-]
+ Discovered an interesting problem that I will
describe here in the hope that you may have
encountered a similar problem and can help
shortcut the troubleshooting process:
My front SU carburetor is not supplying fuel at
the correct mixture. I mean, it is WAY too lean.
When I decouple the shafts and advance the
rear carb, the engine accelerates normally --
and quite responsively I might add. Repeating
the test at the front causes the rpm to drop and
the engine to try to die -- it is supplying air but
minimal fuel. The jet is adjusted correctly and
centralized, the needle is fresh and clean, and
there are no leaks from the overflow. However,
when this carb was first put back into service, it
leaked fuel from the port where the jet fuel line
is connected. It needed to be tightened.
My first thought is that, although I had tightened
the connection correctly when reassembling the
carb, perhaps some of the rubber gasket or a
bit of debris had clogged the junction or the pipe.
My first plan is to disassemble this carb and look
for the problem. Oh yea, both float bowl floats
are new but are the new, non-adjustable design.
