What are they putting in there that just cuts the low end right out  from 
under it???
The winter gas has, for years, produced less HP but this  year is 
ridiculous, I almost thought the old engine had finally given up but  NO... its the 
gas!
 
 
I didn't know they started the winter blend yet. Usually, it's actually  
more gas than the summer blend, since it allows easier starting in cold temps. 
 The summer blend on the other hand, has more oxygen in it, to reduce 
emissions  blended with sunlight. This means your car should run better on the 
winter  blend, since it's more of a real gas blend versus the summer blend. 
Keep in  mind, that the cooler temps require longer warm up times, and this 
might be  part of your problem. 
But, it could be that you're dealing with worn out parts, that you keep  
trying to nurse more mileage out of, and you're seeing that difference now.  
Didn't that engine have 135K on it? And by your own statements in the past,  
mean it's "over due for a rebuild"? You could actually be dealing with low  
compression, and you're trying to tune around it. Or, like Jim mentioned, 
the  distributor could be getting worn out too.
When I ran a set of Dell 36 single throats on a bug, I was always tuning  
on that engine for day to day differences in weather. I finally got fed up,  
and returned the engine back to a single carb, and everything was good to  
go. Turned out, it was also low on compression when I finally went in and  
rebuilt it. 
 
You didn't put in some E-15 (yes it's starting to make it's way thru  the 
system) by mistake did you? That stuff requires re-jetting, and more  
ignition timing to run right. :O
