SOURCE: Adjustment for carbuerator on Poulan Pro Chain Saw/ Model 221/ 40
Are the jet screws fitted with slot heads or 'D' heads? 'D' heads require a special tool to adjust and are not available to the general public, so you are stuck with taking the saw to a servicing dealer for adjustment. Slot head screws can be turned with a small flat-blade driver by anyone. In case you have owner-adjustable heads, try the following: Turn both screws CW to stops (lightly), then back each out 1-1/2 turns CCW. The engine should run with this basic setting. Warm up the saw, then pull the throttle full on. Turn H needle CW until the engine speeds up somewhat, but still 4-stroking. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Release the throttle and adjust L CW until the engine idles fairly well, but allows the engine to 'follow-the-throttle'. Adjust idle speed so that the chain stops turning, but the engine continues to run. Hope this helps!
