Jerry,

Could be a lot of things.  FWIW, try driving at a steady 45 or 50 if you can 
with a fully warmed engine, then pull in your yard or wherever and shut it 
off quickly.  Remove two or three plugs and check the color.  If they are 
toward the white side in color, not quite enough gas.  May have to open the 
main jet one or two thousandths if needle adjustment doesn't help, and float 
level is correct.  If plugs go toward black, too rich and have to go the 
other way. If you are able to measure carefully, a float gage can be made 
from a piece of pasteboard.  You will need a repair book to tell you the 
gage size, and where to measure. I am guessing that has electronic ignition, 
so point gap and condition are not an issue.

My "76 with a 300 cid was a dog from day one.  It lost 10-15 mph going up 
every hill in 3 rd gear, although it didn't skip.  When I finally got brave 
enough to ream the main jet .002", it was a whole nother story.  I could 
gain speen going up the same hills and the mpg didn't change.

Good luck,

Charlie V.
