Clutch: I'm guessing it means worn?
IF so, it can be replaced...but, if driven with bad clutch, you may certainly need to resurface the flywheel.
ALSO, that model may need a new bearing while in there, so opt for the best. I'm guessing Hill engr. of UK via either Ricambi, a sponsor on this site, or someone there more easily from Hill direct, can supply the part. My part number probably is different.
Burning a clutch is typically caused by a bad driver. Nothing more, or just worn over time which is nothing less than to be expected either.
Guessing, Mr. fayed
[I'm sure he kept it in order] kept most up to date.
BE SURE TO ASK WHEN AND HOW many miles ago the last belt change was done.
Also, post your pics and talk to the UK crowd, there are a few in here, and they are helpful.
