Rochester 4 bbl adjustment

[NHGuy]

I have a 1988/89 5.7 Mercruiser MCM with 4 barrel Rochester. I was looking at doing the mix adjustment but waited because the starboard adjuster is a weird reach. In fact the adjustment screws are both a weird metal tab. Do I just use pliers or something?

You use the tool designed for the Q, it`s about 22.00 and comes with 5 adaptors to do the GM motors

I would not chew it up with pliers plus its hard to keep track of where you are. You may find the tool at napa or just use a short copper pipe with the end flattened a bit.
