THe '76 MGB has been back from the shop for a couple of weeks now. The
new cylender head, which allows compression to happen on all 4 cylinders,
has done a lot to improve driveability.
Something new has shown up, however. When the engine is up to "normal"
operating temperature, the idle in neutral slowly increases to about
1600 rpm. For example, if I ease up to a stop light and drop it into
neutral at about 600 - 800 rpm, it will slowly speed up as described.
If I sit with the clutch depressed, this doesn't happen. But everyone knows
that's a good way to use up the throw-out bearing.
It's been suggested that the poppet valve in the throttle-plate is leaking
and that I should just solder it closed. I'm not sure this is a great idea
for a couple of reasons.
Has anybody seen this type of problem before? Any ideas?
