Check the fuel lines for hardness, cracking, splitting, or end rot. Check the muffler for plugging. Check the carburetor fasteners for tightness. Are you using fresh fuel mix? If the carburetor jets have been adjusted, try turning both CW to stops (lightly) then back out each CCW 1-1/2 turns. Engine should start and run--allow to warm up. Pull the throttle full on, and adjust H needle CW until the engine starts to speed up, but still 4-strokes. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Let idle and adjust L CW for fairly smooth running, but still allows the engine to 'follow the throttle'. Hope this helps!

Remove, clean and reinstall the muffler and spark arrestor, if no better the "L" needle may need adjustment.
Carburetor Adjustment by Madsens.com

  • 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.
  • Clean the spark arrestor and muffler; if the saw cannot exhale it cannot inhale.
  • There are 2 wav (sound - idle & full - may not be highlighted) files that I find most helpful, I think you will too.
Most chainsaws die because they are are run lean. I am going to inject a little Lou theory here. Air leaks and defective fuel delivery systems account for most chainsaw failures. Constant adjustment of needle valves can easily camouflage more serious problems that result in burning up your saw.

My e series 142 spins the chain and idles insanely fast when I have the choke pulled out. Then when I give it throttle it calms down and then I can barely keep it idling. with throttle all the way pulled...


Check air filter- clean or replace, Make sure you have fresh fuel, A new spark while you are giving it a service, Do you know how to tune the saw? Start with basic settings 1 turn on the low and 1 turn on the high And adjust from there, You might have turned the idle up too high. The choke should always be fully in when saw is running. Hope this is a good start

Hi, I just cleaned my Poulan Pro. Changed out the gas, opened the carb and flushed it out with fresh gas, cleaned the fuel lines, the spark plug and air filter. I didn't replace the fuel filter though. ...


The fuel pick up or filter should be changed every year but if your saw will start and run good but just not idle then adjust the screw marked T counterclockwise slowly until chain starts to rotate without you depressing the throttle.At that point back it off about 1/16 of a turn until saw will idle but chain doesn't move.Thank you. P.S. If you want to you can go back to factory setting by turning H & L fully closed then open 1 to 1 1/4 turn and very slowly adjust for smoothest operation. Do not adjust H anymore then minimum off factory to avoid engine damage.
If you need further help I would suggest you have a trained tech.service it. Good luck.

How to get the clutch off on a 142 husky


  1. Turn off the saw and release the chain brake. The chain brake is the plastic handle located on the topside of the saw's body, and is between the bar and the throttle. With a gloved hand, spin the chain to ensure the brake is off.
  2. Use the wrench to loosen the bar nuts until they are finger tight. Use the flathead screwdriver to loosen the bar tensioner screw. This screw is located in between the bar cover's two metal posts, and can be reached through the small, round hole in the cover's center.
  3. Finish loosening the bar nuts and remove the bar cover. Take off the bar and chain; set them aside in a safe place.
  4. Unplug the spark plug from the rubber spark plug connector, located on the top of the saw's body. Push some of the chainsaw's starter chord string into the spark plug cylinder to block the piston from moving while taking apart the clutch.
  5. Remove the clutch assembly with the clutch socket wrench. Husqvarna chainsaw clutches are left-locking nuts, so you will need to turn the bolt clockwise to loosen it. Tap on the socket's handle with a hammer if the bolt won't loosen.
  6. Remove the bolt and pull off the clutch cover, clutch spring and clutch drum. Replace these parts if they are chipped, warped or heavily worn.
  7. Follow these steps in reverse order to reassemble the clutch.

Can get it to run but snap throttle it boggs down and some times dies tryed changeing fuel cap with a bran new one tryed ajusting mix screws new plug gets bettter but problem still there


Check the fuel filter, air cleaner, and muffler for plugging. Check the condition of the fuel lines for decay or other damage. Check for spark at the plug--it should be blue and snappy (gapped 0.020"). If it looks weak, try a fresh plug first--if still weak, remove the left side engine cover to expose the flywheel and ignition module. Turn the flywheel magnets under the ignition module, insert a thin business card into the pole gaps, loosen the module screws to allow the module poles to contact the magnets. Tighten the screws, and rotate the flywheel somewhat to remove the business card. Rotate the flywheel one complete turn to make sure the pole gap does not close up further. Reassemble and test for spark again. This process seems to have fixed a lot of Poulan saw problems. Finally, turn both carburetor jet screws CW to stops (lightly), then turn each 1-1/2 turns CCW. Start the engine and allow to warm up. Pull the throttle full on, and adjust H needle CW until the engine starts to speed up, but still 4-stroking. Correct adjustment is when the engine still 4-strokes when running free, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW until the engine idles fairly smoothly, but will still allow the engine to 'follow the throttle'. Adjust the idle speed screw so that the engine continues to run, but the chain doesn't try to turn. Hope this helps!

I have a McCulloch MS1636NAV chain saw. The engine starts with the choke pulled out. When I push the choke in the saw dies. I've changed the spark plug, replaced the air filter. changed the gas, 40:1.


Its either sucking air in throgh a loose connection in the fuel line or the carb is stopped up. Take it apart very easy so you don't rip any gaskets, and clean evertthing with a can of compressed air blow all the tubes out real good. You may have to get a carb kit it that does not work.

But that sounds like what it is, running out of gas when you let more air to it.

Saw starts then dies. Changed fuel ine soaked carb


Check the fuel filter, air cleaner and muffler for plugging. Was the carburetor disassembled when soaked and did you use compressed air to blow out all passages? If the carburetor jet screws have been moved, preset them as follows: Turn both H and L screws CW to stops (lightly), then back out CCW each screw 1-1/2 turns. Start the engine and allow to warm up. Pull the throttle full on and adjust H CW until the engine speeds up somewhat but 4-stroking. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Allow to idle and adjust L CW until the engine runs fairly well, but still allows the engine to 'follow the throttle'. Adjust idle speed screw so that chain stops turning, but the engine continues to run. Hope this helps!
