Rattles on an Elsie

[stuboy]

Excuse my ignorance but its ages (28 years !!) since I played on Elsies and since then been a car driver.
I know two strokes rattle before you all think I am an idiot.
If the engine rattle stops when the clutch is dipped does that mean its just the gearbox//clutch rattling and that the top end is sweet ?

Would think that if the rattle stops with clutch lever pulled then its clutch related as you say yourself......always worth a peek if you fancy dropping the water and oil
