[T3] The Winter Gas

Well, yea, this engine is up to 138K now, but it still cranks fine so I
haven't lost a cylinder yet.  I thought of a flat cam, but then it would go
the other way, Id have low end but no top end, the cam has about 170K on it.

Ive been thru the distributor in recent years and it got a full tune-up last
fall but I suppose something could have given way.  If its not better in the
spring Ill have to go thru and check things.

I just did the gas mileage and its rather crappy too, roughly 24 to 25 on
the highway, and I suspect it needs to be a smidge richer, any leaner and it
really starts missing under light load.  That not much better than the 2056
was, hate to think what the 2056 would be getting on today's gas!

Thanks

Keith

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
