thanks jeff for reply.
used mine a lot for several years, and now cant run and jog like i used to. bike is coming back into play.
i should have left well enough alone but it needed cleaning, but since putting it back on i get it to move from large cog to smallest cog, but after slowing down and stop it wont move back to larger cog as flywheel weights dont want to come back together and close. so some adjustment is out of wack.
nothing seems broken, and springs inside do not seem serviceable,but look intact.
i have origina l manual have read it multiple times
reminds me of an old swisss mechanical cuckoo clock, just neds right adjustments.
if i cant get it to adjust i have thought about taking it off replace with a standard cable deraill,rear wheel, hub,and v pulley should not be an issue i dont think.
