Rod,
Carby settings are:
'L' screw you bottom then back off 1 & 1/8 turns
'H' screw you bottom then back off 1 turn
Plug gap 25 Thow
The third screw is the idle speed and this should be adjusted so that when the saw is idling the chain should not move.
I can supply a parts list for the machine just e-mail me under spare parts this site.
Fuel filter is located in the tank and also you have one in the carby as well.
Regards,
Bruce
