I still like the fuel starvation theory. I had a similar problem with my
other car*. After cleaning the fuel filter, tuning the car, replacing the
fuel pump,and other unsuccessful efforts, I found that the valve seat for
the needle/valve assembly to the float bowl had loosened, lowering the level
of fuel in the bowl.
It could be coincidental that the problem occurred after the valve job. But
when in doubt, look at all the possibilities.
*The other car was Japanese (Toyota Landcruiser) which I did refer to as a
"Jap" car on this list. One reader suggests this may be offensive; however,
I used the term merely as a shortened word. One must look at intent -
besides, using offensive terms with one's car only invites mechanical
breakdown. My Landcruiser is much like my BGT - treated kindly and used
routinely, it will be reliable.
