Poulan 2150 saw will not start.

SOURCE: can,t hardley pull starter cord. I've removed

What i have to occasionally do for a chain saw after it sits all winter is to put something like WD40 in the spark plug hole and crank it over several times. What happens to me is that the piston gets gunked up from the gas that ran down into it during the winter and it won't crank over hardly at all. This is probably your problem. I have also found that if i store my saws with the tank down, the gas cant get into the carb and do this. (Although it's better to drain tank).
If this has been a running saw instead of a stored one, you probably need a rebuild kit if the piston is scored.

SOURCE: Husqvarana Rancher 55 , how to clean the exhaust port

Cleaning the exhaust: on the saws I've worked with it was just to loosen two bolts at the front and then the exhaust is off the saw. Clean with brake cleaning fluid and blow with compressed air, let it dry before assembling. Don't forget to clean the fine mesh at the output side underneath the lid if present (i.e the spark arrestor).

Make sure to have your carb adjusted properly afterwards.

I suspect your ignition module is bad try this.

You may need to use a jumper wire between the threaded part of the plug and the cooling fins. There is no need to bend the electrode. HTH

It may be flooded too. You shouldn't need to choke it for more than 2-3 pulls.
Husky (cold):
1, Ignition on/off to on
2. Pull (close) choke (also sets fat idle); pull starter and listen for an attempt to start. once heard (usually twice)
3. Push (open) choke (fast idle maintained) pull starter until it starts. Usually first pull)
Warm:
1., 2. (without pulling starter), 3..
Hope this helps

Testimonial: "recommedation very useful thank you. you guys are good."

It is running lean. There is an air leak somewhere allowing to much air into the cylinder or crankcase. Continuing to operate lean may cause failure. If fuel delivery lines have no pin holes or cracks probably time for some professional help (pressure tests). Remove clean and reinstall the muffler (carbon fouling can also cause this). If the saw cannot exhale, it cannot inhale. HTH

Clean the muffler spark arrestor screen and check the cylinder port for carbon build-up at the upper edge. Try presetting both carburetor H and L adjustments (from lightly CW stops) 1-1/2 turns CCW each. Start the engine and allow to warm up. Pull the throttle wide open and adjust H CW until the engine speed increases, but still 4-stroking. Correct setting is when the engine 4-strokes, but immediately 2-strokes when cutting. Allow to idle and adjust L for smoother running, yet allows the engine to 'follow the throttle'. Set idle speed to keep the engine running, but doesn't try to move the chain. You may have to look closer at your carburetor if the above doesn't help. Go to:

for an excellent article (but poor pix) on Walbro carburetors, but related to most all 2-stroke carburetors. Hope this helps!
