    42cc craftsman about 5 yrs old I need to adjust the carb but can't figure out what tool I need

    the idle can be adjusted with flat screwdriver but the other adjustments I can't see in the holes to tell what type of tool I need

    I eventually want to muffler mod this thing


    thanks

    you can find the tool on ebay very easy, or:
    pull the carb and grind slots in the jets with a dremel. no more special tool needed:greenchainsaw:

    Should be the same small flat screwdriver in the other adjustments too...

    I believe that is the same special tool that the poulan crappything uses. It's avaiable on Ebay or many of the Jred and Husky dealers can get them, as a 3 are owned by the same parent company.

    The knurl might be what shows after the original limiter caps have been pulled off. Most new saws are leaned way out at the factory to meet emission limits, and the caps get removed to permit proper adjustment after break-in. If no slot is there on the needle valves, use a length of fairly firm plastic tubing that fits snugly against the tapered knurl. Unscrew the needles and flatten and slot the ends with a thin cut-off disk on a dremel or with a thin flat needle file.

    the poulans he's talking about never came with limiter caps. the special tool is their way of preventing people from adjusting the jets.
    you won't turn the jets with a piece of tubing, the springs are too strong. you need the tool or a slot to turn them, hence the info given earlier.

    You can do as you say to put a slot on the end of the needles, but it's a PITA to get a screwdriver on them when the thing is running, too much room in there to guide the screwdriver in. The tool makes it slick and easy.

    I just removed the limiters from a 2150 today, and the Poulan tool fits perfectly evan though they have a screwdriver slot in them, it's much easier this way.

    Zama carb?

    If you dont want to go by the service place or wait a week on the tool, you can try a wiring butt connector. Slide the wiring connector down over the splines and see if it will grab tight enough to turn. You may have to take the recoil side cover off to get in there. If that wont work you can try a section of a brass tubing that you tap on over the splined jets. You can buy the brass tubing at any craft place or hardware store. 1/8 inch ID is just about right.

    Consider removing the jets one at a time and slotting them with a dremel or a hacksaw for future use.

    Best wishes,
    Bob
