Hi ifwas...

Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:
Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of most chainsaws.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the chainsaw is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
Note:
The little spring inside of the carburetor goes under the float arm.
That is where your fuel inlet needle/float valve is located...on the arm at the end.
Normally there is a small indetion in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.
The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.
Once you have your carburetor cleaned/rebuilt that should solve your problem.

Yes u can do this, take gas line to a farm equipment store ( hardware store may not have the correct size) they sell by the foot.

If the saw is brand new, take it into a service dealer for a carb adjustment (covered under the warranty). This sounds like it is your issue and unfortunately, you cannot correct it yourself because it requires a special tool.
As for you manual, it is located at the link below http://weborder.husqvarna.com/order_static/doc/NOUS/NOUS2006/NOUS2006_545137248.pdf

The fuel tank is integral with the plastic housing of the saw. A leak has obviously developed, I would say its time to replace the plastic housing and go from there.

Hi llamalodge20...

40 to l is too heavy with oil....try 50:1...One pint of 2 cycle oil to 6 gallons of gasoine.
Please take time to rate me

Unleaded fuel mix with good two stroke oil at a ratio of 25-1

Its either well flooded, or the carb needle is leaking, remove the spark plug, with the ignition switch off crank the engine to evacuate any fuel left in the cylinder, leave the machine for a couple of hours, re fit the plug and try to start useing no choke, if it still does not start, remove the spark plug again, rest it on top of the cylinder ( away from the spark plug hole ) crank the engine and check for a spark, if it has a good spark and the plug is soaked with fuel it could be a carb needle leaking, remove the carb, remove the metering cover held with four screws, replace the rubber tipped needle.

hi there

jesnebres

pauly46 here

here is web site for parts it has breakdowns on just about every model

http://www.ereplacementparts.com/poulan-2150le-predator-type-gas-chainsaw-parts-c-16962_17147_17229.html

this site is cool its got helpful vids to show how to's

can order parts on this site

have a peek

cheers hope this helps

The oil to gas ratio is 40 to 1. If my math is still good this works out to 3.2 ounces of oil to one gallon of gas.Hope this helps and thank you for letting me help.

Sounds like a valve is messed up or a piece of carbon stuck in the exhaust valve that won't let close.Fairly easy to fix except the spring keepers a little tricky.You will have to remove head but there should be access to at least check the valves out. Thank you for using fix ya.

40:1. Please take a moment to select a Rating if this has been of any help. Good Luck,, be sure and use clean new fuel

Hi above is a manual and inside is an exploded diagram for you so you can see whats what.


I fear that the cable for the choke has somehow become detached from the choke opening arm?

Nothing you could have done would cause this to happen.

However if this were mine, and this happened i would take it straight back to the shop, and ask for an explanation? and for a FREE repair.

This shouldn't happen at all ever, more so on a new device.

The air gap for the flywheel is 0.3mm and the plug gap should be 0.5mm

Usually when a small engine starts fine.. runs fine.. gets hot it's ignition related.

First you want to make sure the cooling fins are clean.. remove any covers and clean the area around the head. If those fins are clogged.. not good.

Second I would check the spark.. and the spark plug condtion.

Also for power tools that don't get used that often.. fuel sytems get gummed up.. fuel gets old.. and folks tend to use the fuel in the can they mixed two seasons ago. Make sure the fuel mix is correct.

I assume it is running fine with the choke off.. however check the choke for proper operation.

Clean or replace the air filter as well.. once all the ignition and fuel components are in good order.. only then should you begin to adjust the carb. Probably not needed.. but don't do it until you are satisfied that you have good air fuel mix and proper spark.
Best of luck

A couple of ideas, it could be a fuel tank breather issue, when it starts to die just try loosening the fuel cap, if the saw picks up again you will need to change the breather, the only other thing i can think of is a bad ignition that is breaking down when hot, the only aswer to this is to replace the ignition unit

Check there are no kinks in fuel line.
Make sure that the air filter isn't blocked.
Check the throttle cable is operating the throttle plate in the carburettor ok.
Ensure chain isn't too tight.
The carburettor should be a tight fit on the air inlet manifold.
It's possible that some of the jets could be blocked in the carburettor. You can try and clean these with compressed air but ensure you remove any seals gaskets, springs on the diaphragm pump , primer bulb etc as they can be damaged by the pressure.
