idle adjust

hi all, has anyone got any pics of the idle adjustment screw location? also i hears the o rings perish on them?
i think ive located it on the back of the throttle bodt(bulkhead side) does it have a bung covering it?

also where is the mixture screw?

On the back if the throttle body.

Just replaced mine and it immediately sorted my idle problem.

Was very flattened when i removed it.

New o ring was much tighter fit when I put the screw back in.
