J.A.P spares required

Hello
I own a J.A.P.   C/80/F  two stroke engine fitted to a Trac Grip power barrow  cira 1954.

I am looking for engine spares, can anyone help or advise.

Tried a couple of people listing that they can supply J.A.P spares but nothing for the C/ 80/F  

This is an 80cc J A Prestwich 2 stroke.

Can anyone tell me what the C & F parts of the engine model indicate.

Parts mainly required will be a recoil pull starter, carburator (make B.E.C)
Metal head gasket


Thanks  JOHN
