I am installing a new carb on a Stihl BR550Z blower. The problem I have ran into is that Zama has changed the mixture adjustment screws. These are hex shaped and are recess. What I need is the tool pn or at least the size of the hex which I am assuming going a metric size.
Numbers on carb is 100348A 4282/12A 542A which of course don't the normal numbering scheme that I am familiar with. The Stihl carburetor part number is 4282 120 0612.
