talking with a few poeple its seems that its most likly either my fuel filter, which i hav never changed, meaning it could be over 100000k's( ) ... so ill get a new one of those, or more likly, that the carby is in need of a good clean.
if i can be bothered, ill rip it apart this weekend and give the carby a clean and maybe whateva else i can find.
fuel filter ill assume is an easy procedure. i havnt looked, but ill assume they are befour the fuel pump, so are fairly simple to exchange.
as for the vibrations in the brake pedal.... i might do a fliud bleeding... but not really that converning atm.
