IMO I would remove the air filter and spark plug and clean them first, check for loose carb. mount screws. Start the saw and run some carb cleaner through it. If it still stalls I would try to adjust the high jet counterclockwise about 1/8" to rich up the mixture alittle to see if that helps. Note where you adjustment screw were so you know where they was orginally if that don't fix it.

Thanks rc, for your response. The spark plug is good and the air filter clean. I will check carb mounting screws and clean, then adjust if necessary.

The carb adjustment screws are round with a flat on one side so a specific type of tool is required for adjustment. The screws do not have screwdriver slots. I guess it's so dimwits like me can't make adjustments to their own equipment. A very small screw driver can do the trick by twisting it against the flat but this is tedious. Do you know if this adjustment tool is available for purchase to the general public?

The tool is for dealer shops. The EPA does not want the emission settings changed but unfortunately they create the over lean condition you are experiencing.

Thanks canguy for that info. At least there's a reason other than profit for having such a configuration on the adjusting screws.

My problem was that I needed to adjust the high limit for the carb. BTW I figured out how to adjust it without the stupid tool. Just angle a small screwdriver against the top of the adjustment screw and oriented in the direction it should move, then tap with a wrench or other object (I used a 3/8 open end wrench) and the screw will move. Of course, the top of the screw will get a little buggered up. A swiss file with a tapered tip will clean this up with little effort. An unorthodox repair, maybe, but I probably saved myself about $80.00 for a technician to turn the special tool about 1/8 of an inch!!!

Hey rcmoser, you're advice to turn screw CCW about 1/8 of a turn was right on. I probably just went a little past 1/8.

Now I will take out any left over frustration on an ugly Azalea in my yard. Thanks again everybody.

You can find the carb adjustment tools on ebay the D shape one is really hard to find. I've only seen one in the last 6 months and it went for over $20 bucks. If you can get the adjustment screws out you and take a 1/8" grinder tiny cutoff wheel and slice a screw driver slot in them. Sometimes small needle nose pliers may work also.

You are right they don't want us knuckleheads tampering with them, but some are so lean depending on where you live the won't run unless you leave the choke half on.
