Re: Fuel Filter Question on Carter WDO carb

That is an interesting device and would be even more interesting to know the theory behind how it is supposed to help fuel economy. Seems like anything it could do before the carb like starving the fuel flow or lowering pressure would be messing with the carb adjustments and if that is what it does then I would think all kinds of drivability problems would occur.

I remember the gadgets that filled the pages in the JC Whitney catalog when I was a kid in the 50s. All sorts of wondrous things to increase power and speed and then others to help economize while you did the first two. Without knowing more about how it works, my first thought is it kind of sounds like that one would have been right at home in those pages.

The heat shield was standard with the 356 engine but does not appear to have been offered on the others. There is a thick insulating spacer that goes between the carb and manifold on all models to help with the control of heat soak but I am wondering how much either actually helps. The increased volatility of todays gasoline probably has a great deal to do with the many flooding when hot issues people are reporting now.
