John,
Have you checked your timing or vacuum advance. On my 72 B I noticed a lack
of power and it turned out to be the vacuum hose to the distributor was
plugged or collapsed. Replaced with new rubber hose and it works fine.

Subject: Sputtering problem.
My 1974 MGB has recently developed a problem were if I try to accelerate to
fast, or if I go up a hill, the car starts to sputter. If I back off the
throttle a little, the sputtering will stop. If I nurse the car while I am
driving it, it is not too bad, but it is considerably less fun to drive. :o(
Plugs are tight and clean, cap and rotor are clean, air filters are
clean. I am thinking it is either a vacuum leak, or the carb jet is
sticking. I am planning on trying to attack this problem this week. Do
you guys have any other ideas of things that might cause these symptoms?
FIY: I am running the stock distributor (with Crane electronic ignition
mod), stock HIF SU carbs, stock air cleaners, engine has been
de-smoged. Please also note that the car ran fine for 6 months. Now
within the last two weeks this problem has started.
Any ideas?
Thanks in advance.
