Other Poulan Chainsaw Carburetor Adjustments
A basic procedure is to start the saw, turn the screw clockwise until the engine begins to stall for lack of fuel, then back the screw off until the engine stalls because it has too much fuel. The ideal setting should be midway between these points.
There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. These often look like flat-head screws, and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carb.
The letters on the screws represent High (H), Low (L) and Idle (T). The H screw regulates the Air/Fuel mix during high RPMs, while the L Screw does the same during low RPMs. The T screw regulates how much fuel is sent to the carburettor while idling until the throttle is pressed.

CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly. Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.

How to adjust carburetor on Poulan FL1500 blower
ANSWER : The L and H mixture screws have unorthodox heads on them, but they can be turned. You can buy a tool for the type of head they have on Ebay. I use a plastic automotive type wire terminal connector and tap it over the head of the mixture screw. The 22 gauge ring-eye type works well because it gives you something to grasp and turn the screw with. Here is the manufacturer’s tutorial on adjusting your carburetor.

ANSWER : Are they two separate screws? one for fast, one for slow.for the slow setting, first start the saw then screw until motor runs smooth without chain moving….if to slow the motor will stop….for fast screw….rev motor flat out then adjust so it screams its head off so to speak….it will need all its power for cutting wood so don’t think you are opening it up to much as its designed for it.
