It's a good suggestion, but a loaded one without the right tools as the mixture screw is stupid sensitive to even 1/16 of a turn.
Messing with the mixture screw without analyzing the duty cycle from the ECU or CO2 from the tail pipe in an effort to compensate for air leaks or bad fuel pressure can cause all sorts of mischief. It is a great way to fail emissions (if you live in a state that does them), get poor performance, and add to the likelihood of destroying your catalytic converters.
The screw should be the last item one touches when getting this system in tune considering how it is possible to go from running to too rich/lean to start by turning the screw more than a 1/4.

Avoid the temptation to mess with this unless you've got the corresponding tools to correctly interpret what's going on.
