I'm fairly sure the stock mechanical pumps are similar to those used on the
L-motors and doubt that your pressure's too high. If that were the case I'd
expect to see gas coming out the float bowl vents and overflowing
internally, too.
I'd guess it's a case of the two metal matting surfaces not being exactly
parallel all of the way around the pump and the gasket not having enough
squeeze (okay compressibility, for the technical types) to fill the
irregularities gracefully.
The more Solex experienced on the list will have to say if the following
might work or not, but I'd consider stacking a couple of gaskets or making
your own from some gasket material that's slightly thicker and more
compressible. I doubt that doing that will alter the accelerator pump shot
enough to hurt, but I could be wrong.
FWIW, Ron
