MGB/GT Heat Related hesitation - vapor lock?

[Scott Williams <wcs@cjnetworks.com>]

Hi again list,

I wrote about the heat-related issues I was having with the 1974 1/2
MGB/GT. I think I have tried most everything that was mentioned. I
talked to a friend who has several British cars that hate hot weather.
He contends that fuel is made differently for emissions these days and
that its just a plain old vapor lock condition that I'm experiencing.
Anyone else having issues with acceleration problems in this really hot weather?

Thanks
Scott
