The old boy I ride with tells me the idle mixture adjuster screw is an air screw on this Amal...yet I've always thought if the screw is engine side of the slide, it must be a fuel screw?

 

So who is correct?

Fuel screw...wind out for more fuel

Air screw...wind out for more air

Bike is a Montesa 247C 1978 but an Amal is an Amal I guess?

 

cheers guys
