Husqvarna Chainsaw 266xp

The starter pull cord is really difficult to pull over so I removed the spark-plug and the engine pulls over effortlessly. I suspected a blockage in the exhaust muffler however after removing this I still have the same issue. I've checked the piston and it looks clean and undamaged so I'm now suspecting that the issue is with the air-intake. The carb air-filter is clean so should I be removing the carb to see if it pulls over or not ? Regards Tim

The 266XP never had a deco valve, once the ring bedded in they did have a really good compression, the is no milage in removeing the carb, you can remove the cylinder and fit an additional base gasket, you can also increase the air gap between the flywheel and ignition unit, this will cut down some of the drag from the magnets, once you have done this there is little else to do, it is what it is.

SOURCE: Husqvarna Chain Saw Rope Pulls Very Hard, what is the cause?????????

Has it always done this or has it developed?
Some saws have a decompression button to make it easier to pull over.

SOURCE: engine will not roll over using pull cord. removed

sounds like possible piece of carbon sitting at the top of the piston or top of cylinder.when the piston gets to top dead center it's trying to squish the carbon not letting it roll over smoothly with recoil.

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: pull cord difficult to pull..removed from saw it

Make sure someone hasn't run this saw without the oil in the fuel mixture. It is possible it is dry and some galling is happening. Or - if this saw is equipped with a compression bleeder (for easier starting), this could be not functioning and you're pulling through the normal compression (which can be a bit feisty!). Check for misalignment of some type having to do with the pull starter - check that the cord spool isn't rubbing on the housing when you pull. Good luck.

SOURCE: McCulloch chainsaw 338 wont start

Unfortunatly this machine appears to have seized on the piston, there is no other answer but to pull it apart and see how much damage has occured, it may well be beyond economic repair, as it will probably require a cylinder and piston.

Stihl chainsaw MS460 Can't pull recoil

It could be the recoil is stuck. a couple of things to check. Take the clutch and chain cover off, remove the spark plug and manually try to turn the motor over by turning the clutch. If the motor/engine is not seized, take the pull start/recoil cover off and pull on the cord to see if it will work and that the cord returns back into the recoil automatically. Don't take the nut off the inside of recoil holding the cord spool on. If the engine is not seized, and the recoil now goes in and out by pulling the start cord handle reassemble and pull over the engine a few times. This a good time to check the spark plug is working, now put the spark plug back in and start the engine. It's a good time to clean the air filter as well while the chainsaw is mostly apart and clean all oily sawdust off the chainsaw in the crevices etc..

Saw starter pulling too hard to start.

Check piston rings. Sounds like you have a seized engine.

Starter rope grabs at times. why?

try using the de-compression button when starting, will do the same as removing the spark plug but without removing the spark plug.

Failing that, remove the starter cover and check starter cord for daage or signs of snagging.

Compression in cylinder too strong to pull starter cord, can remove spark plug and will turn over, replace plug and will allow one pull on cord

We have a Husky 435 that does the same thing. Found that the engine is trying to fire after first pull. Try setting the choke at 1/2 after first pull, but don't bump the throttle which will release 'fast idle'. This process seems to limit the 'kick back' effect. It also helps if you have a strong arm. Good luck!

My Chainsaw Husqvarna 345, won't start. With

I hope 2 different problems Marvin. I think the starter is most important, after you reply with findings we will take on the likely fuel delivery problem. Please do this and post back (below) with what you find.

Starter Handle difficult to pull:
1. Remove the starter cover. Does the starter operate smoothly? If yes, reinstall the cover and continue with 2, if not repair the starter.
2. Is the saw equipped with a decompression valve? Yes continue, no proceed with 3.
· Leave the ignition off, set the valve and pull the starter.
· Pull gently to release the valve. Is there a difference in the effort required?
· If yes continue with 3, if no repair or replace the decompression valve.
3. Was this saw perhaps operated in a lean condition (metal transfer from the piston to cylinder wall)? This may be caused by many things including but not limited to; leaky intake connections at the engine or carburetor; leaky crankcase seals; cracked fuel delivery lines; running on gasoline containing no 2-cycle oil.
· Disconnect the spark plug wire and remove the plug. Remove the muffler (clean it and the spark arrestor before reinstalling), hold a light at the plug hole and inspect the cylinder through the exhaust port. Is it smooth and shiny or does it appear speckled with dull gray spots or smears?
· Pull the starter slowly, inspect the piston as it rises and falls. Is it a dull gray without scratches and gouges?
· Hold the light at the exhaust port and look through the spark plug hole, inspect the cylinder above the exhaust port. Is it shiny and smooth or speckled with gray spots or smears?
Please Note: Any spots or smears on the cylinder or deep scratches and gouges in the piston indicate the saw was operated in a lean condition. Repair of this on a home owner quality saw often exceeds replacement cost. A repair estimate by an independent saw shop should be considered.
4. The last likely possibility is the saw has jumped timing. Inspect the flywheel and crankshaft under the starter cover. Are the woodruff key slots aligned and the key intact? Please take it to a good local saw seller/mechanic for a written diagnosis before authorizing any repair.

If you have more questions or need additional help please reply below and I will get back to you. Thank you for using FixYa and Good Luck. HTH
Starter fluid removes what little lubrication is provided by the fuel mix. I suggest a teaspoon of mix into open carburetor throat or the plug hole. Do not go to speed with the air filter removed.

Won't crank, thing next to spark plug keeps popping up

Jerry is correct the compression release is ajdacent to the spark plug. If it pops the saw fired and the release closed (what it is supposed to do).
Read page 22 here:
Excerpt follows: "Pull the starter handle (D): Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull firmly and rapidly until the engine fires. Push in the choke control as soon as the engine fires which can be heard through a "puff" sound. Keep on pulling the cord powerfully until the engine starts."
Continuing with the choke closed causes flooding. Please read the "Warm Engine" too it is slightly different.
Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week.

I tried to start my older Poulan Chain saw a day after I had been using it. I find it almost impossible to pull the starter cord...there is too much resistance. If I take out the plug and pull the cord...

Did you remember to mix oil with the fuel before you put in the tank?

Remove the spark plug wire and the spark plug. Remove the muffler. Shine a light through the spark plug hole and inspect the cylinder through the hole where the muffler was. Is it smooth and shiny? Use the starter to move the piston up and down slowly. Is it smooth or does it appear scratched and gouged?

I suspect parts of your piston are adhered to the cylinder wall. If that is true it will probably cost more to repair it than to replace it.

You needn't take it to a poulan repair center. Most Stihl outlets employ good mechanics and can repair any saw. HTH
Shh... my Husqvarna gets serviced by a Stihl dealer... The Husqvarna dealer is actually closer to me. I feel better about the Stihl mechs.

Starter rope will not pull. Will pull smoothly

If I understand what you are saying... The starter pulls smoothly with the starter cover removed or when installed and the plug removed (no compression or spark). If this is correct I think your saw's timing has slipped or maybe a defective decomp valve. Time to visit your neighborhood chainsaw seller/mechanic.HTH

Husqvarna 51 from 1991 too much resistance to starting attempts

It sounds like it's sorta gummed up from old gas residue. You could spray carb cleaner in the spark plug hole and into the carb while holding the throttle open and pull the cord several times and then follow that with penetrating oil to re-lubricate the engine. You're probably going to have problems with the carb also. I would have it rebuilt or, better yet, purchase a new one

sound like hydraulic lock,try leaving the spark plug out and pull it quite a few times with the spark plug hole facing the ground, this should shoot the offending fluid out.
