Hi guys,
 Could anyone tell me if there should be some sort of screw that goes under the Airflow meter sensor plate as ive rebuilt the engine and noticed a hole with threads in when reassembling cheers

The little tiny screw for adjusting the flap position? or is it something else...

Hi Not sure as I can't figure out how to post a pic to the site, I think if there was a screw in the hole it would lift the flap yes

You need that to adjust the fuel mixture.
Replace with an allen type screw so you can use a long t key to adjust.
