Contact member Dillen (Martin) and he will certainly provide a capacitor kit along with full fitting instructions. He can also supply a brand new tacho disc (in S/Steel) as yours will certainly have started to fail if it is the earlier cellophane type.
Can I also suggest repeating this thread to the Beogram section where it is likely to gain a better audience for your problem (Dillen seems to spend a bit of time on there helping other beogram owners)?
Chris.
The use of metaphors should be avoided like the plague. They're like a red rag to a bull to me.
