After i changed a flat the other day i left a bit of a dirty spot on the rim i forgot to wipe. so on the next ride out, the dirty spot was smooth and it caused a brake pulsation. but as the brakes pulsated, the bike felt extra rough and bouncy feeling. I checked the headset with the front wheel against the wall etc. and there was definitely some movement, but my bars spun pretty smooth. but just to see i tightened the headset to a little on the rough side. and still it felt like there was alot of movement between the front wheel and the frame. it felt sort of springy though, as oppose to jiggling like a loose adjusted bearing. I only weigh 140lbs BTW. bike is my '78 raleigh competition 531.

how likely is it that my fork could be failing? the bike was pretty rusty inside and out when i got it...
I'm ordering a tange headset right now any way, the old campy on here has seen better days. although i'm sure i'll have to re-use the upper anyway.
