could someone please help with the following:
1     best procedure to fix faulty silicon rubber switches (i have seached
the archives for same and found a lot of comments , but for some reason the
"solution " was deleted. so all in all that avenue was about as useful as
an ashtray on a motorbike!!!!!!)
2     scaling / tuning procedure 
3     website address for service manual?
thanks in advance
