fuel mixture screw?

[dmagavs]

i unscrewed this today a bit much and think something fell out from inside this screwhead housing.

so is there something meant to be inside this (rubber/spring) and does Vx sell these

heres a pic of the part im on about with the red square around it...borrowed pic from another post in here

thats only a schrader valve to release the fuel pressure from the fuel rail before removing the fuel pipes

[dmagavs]

so its nothing then? i thought it was used to adjust air/fuel - was adjusting it to try n lower idle revs

[matty101]

if your having problems with your idle revs try cleaning or changing your idle control valve. (the other thing circled in the picture)

no thats not what its for, i suggest you buy a haynes manual as you will cause yourself a lot of expense messing around with things you dont know about

[dmagavs]

lol true haynes it shall be then...
