This is a '79 Fuji Grand Tourer btw. I'm having serious trouble shifting from the small ring to the big ring. I've followed Park's derailleur adjustment guide and I have adjusted gears on other bikes without trouble before this one. The issue is the shift from the small to the big ring is very slow if at all. If I adjust the limit screw out to the point where it throws the chain the shift is still just as bad, it just culminates with the chain being thrown. This FD is different than my other bikes in that when the cable is slack the derailleur shifts to the big ring (and yes the cable is totally slack when shifting to the big ring). There is a wobble in the crank but the shift from the large to the small cog is crisp and precise so i'm doubting that is the issue but maybe i'm mistaken. I've also tried lubing the spring in the FD to no avail. Anyone have any ideas? This is driving me nuts.
