<VV> Carb Fuel Filter "Stones"

[David George]

Been having a problem with my 65 vert today in that it idles well enough but 
has power loss under load (feels like running out of gas). Have read other 
threads about it and understand that the problem could range from something 
picked up out of the bottom of the gas tank, to bad coil, to points problem, 
to water in the gas. To give you a little background, the car has been 
running pretty well (a little rough when cold but smoothes out after a 
minute) and I drove it about 50 miles the other day without incident. That 
is, until I turned onto my street. As I turned, the car downshifted and then 
the issue began. Done all the basic checks: linkage between carbs still 
attached and working fine, good stream of gas getting to both carbs, all 
plug wires on and seated well, etc.. I have not read in any of the threads 
that anyone changed the "Carb Fuel Filter Stones" to try and resolve this 
issue. Has anyone done it and did it help? I do have new plug wires and coil 
on order from Clark's and plan to install them this weekend. Just curious if 
anyone has changed the "stones" and if it helped. My gut is that the problem 
is fuel related and not ignition, but some of you guys may know better than 
me. Any advice on the stones and the problem in general would be greatly 
appreciated. Thanks!

By the way, I posted a while back about overheating. I did as many suggested 
and knocked the timing back a bit, cleaned under the shroud (although not 
much in there), cleaned out the oil cooler (very dirty), and removed the 
lower shrouds. Happy to report, no more overheating. No just this pesky 
power loss issue, which I am hopeful will turn out to be minor. Thanks again 
for all your help!
