Power Problem

[RidgeRunner]

Not normally, the mechanical pump is normally all it needs. I don't own one but I do know general info on automobile engines. I recall your post from a while back. Frustrating ain't it.. What have you tried so far?
Have you tried to hook up that inline auxillary pump?

I can't remeber exactly what you did, but did it run correct with the electric pump hooked up? Start with the basics( even if you allready did it a while back), check compresion, check dwell(if you are running points, you really need to convert to pertronix), check timing, and check fuel pressure. If everything checks out, remove the fuel filter from the carb(remove the fuel line and break the big nut loose, screw it out and the filter is behind the big nut), if theer is a lot of trash in teh filter, do your self a favor and go ahead and rebuild the carb, they are not that hard to do
