[Mgs] Glowing B problems~

[Clayton Kirkwood]

I have a 79 B which I started up after 10 years. I had problems with the
fuel pump which was stone quiet until hammer taken on it when it decided to
behave. Fuel lines were brittle from tank to pump to engine compartment and
from plastic fuel filter to carb. Replaced and lots of cranking and the
beastie finally coughed alive after minutes of cranking.

 

Now for the meat. When I mothballed the B 10 years ago, I had a problem
which the "MG mechanic" had worked to right several times with little
success or knowledge apparently. The problem presented today very quickly ~
5 minutes. The exhaust pipe started glowing bright red. Now, I've been told
several solutions: 1) the mixture is too lean and therefore is burning in
the exhaust, not in the cylinder; 2) the mixture is too rich and isn't
burning completely in the cylinder, but is continuing to burn in the
exhaust. 

 

What say you? Is there a problem possibly with the exhaust valves burning?
The car has only 9000 miles on it.

 

Thanks,
