Flooding should be evidence of wet gas in the comb chamber (on the spark plug tip when you remove it or actually dripping out the muffler) If it's dry then your not getting gas up to or through the carb.

Start off in the tank by removing the fuel filter (clean it or replace it) stick the carb. cleaner nozzle in the hose that the fuel filter was pull it off at the carb. and spary carb cleaner through the hose. does it come out the other end? if so you may need to look for cracks in the line, a crack will not alow the fuel to pull up to the carb.

Once you know your getting gas to the carb. clean you carb
Using carb cleaner (in the can under pressure) fluid as air pressure. It will usually blow out the passages and clean/disolve any gum you may have missed. Use the red or black plastic nozzle, but wear rubber gloves and safety goggles or shield cause the fluid under pressure will squirt out about any direction. Once you get it cleaned out by spraying each passage and watching it come out the other end you can reassemble the carb. If I remember set the low and high at 1 1/4 turn to 1 1/2 to start out.

It should run and idle. once it warms up you may have to fine turn the high usually CCW 1/8 turn more. If you turn it over 1/2 turn you may have to go back and adjust the low. If that still don't work then you either have a vacuum leak (seals in the carb., carb mount screws loose or carb. base seal leaking, cracked fuel hose from the tank to the carb. or plugged up fuel filter that will not let enough gas being sucked up to the carb. when the diaphram fuel pump draws it.

Many new chainsaws come with an improper gas-tube length which prevents the pickup to always drop to the bottom of the tank. Test it out with an empty tank. turn the saw in all directions and watch the pickup of the hose fall to the bottom. If it gets stuck at the side of the tank, you have to pull the hose out a little bit with a needlenoseplier. Then cut off as much as is required to let the hose fall to the bottom in all positions of the saw. Now the saw will run until the gas-tank is really empty . Peter Thoss Sept. 21/18

Peter , most quality saws have in tank fuel filter installed on the end of the fuel pick up line which is weighted ensuring no fuel starvation no matter what position the saw is in , even the Cheap Poulan . Not sure what saws your referring too . Also this thread is over 9 yrs old and entitled proper jet set points which is 1-1/4 to 1-1/2 turns out from seated position for both high as low jets normally .

What does CW and CCW stand for?

Clock wise and Counter Clock wise !

Most newer Poulan saws require a special splined adjustment tool. Save yourself the headache of trying to do it without one and just search "poulan carb adjustment tool" for your model and spend the $9 right now. 1-1/4 to 1-1/2 turns out worked as a good starting point for me.

My poulan 2150 will start and run as long as I have the throttle pressed but will not stay running. Need factory settings for carburetor

wait for the answer

1-1/4 to 1-1/2 turns out from seated for jet adjustment is the norm . If required a little less , each saw operated within different elevations and temps , so barometric pressure will have an effect !
