I'msorry, but this statement just doesn't make sense. If the stock air
cleaners are "restricting" the air flow at idle, why aren't they choking it
off completely at open throttle? A quarter million MGBs out there are not
exhibiting "restricted air flow at idle" with their stock air cleaners.
Maybe it's running too rich at idle, but if so it doesn't have anything to
do with the air cleaners. More and more this sounds like a mixture problem.
The new air cleaners are "fixing" it at idle, but exaggerating it at other
throttle settings. The solution is to adjust the mixture correctly, for
whichever intake system you intend to run.
