does anybody know how to adjust the metering head plate cheers

 

there is a hole in between the meaterin head an the air filter,some have a tube thing bolted on an some just a hole. there is a alen key screw wich you can addjust. screw it in(clockwise) to push the flap down. or just take it and have it tuned mate

 

that just alters the co2 mixture the flap on my metering head is sat 2 high up

 

apart from that i dont think there is any addjustment on it. the plate is bolted to the arm wich pushes the plunger on the bottom of the meaterin head. strip it down an have a look inside make sure its all as it should be mate
