My Husqvarna 345 will not stop.

SOURCE: i have a husqvarna 345 run about 4 min then stops

Do you have to wait awhile before it restarts? If so may need new coil.

SOURCE: Where is the bar oil adjusted from on husqvarna 345

Turn the Hus 345 chain saw upside down, you may see a little Icon of a oil droplet and a + - arrow by the chain. THe adjustment screw is not pictured in any of the standard user manuals,. but it is a small black slot headed screw over a rectangale metal tab by the chain. I believe if you turn it counter-clockwise, it will give you more oil,, It did for me. If you have the bar off, you can start the saw and see it come out the hole, that would verify your oil pump is working. Make sure the holes on the bar are clean also. running the saw at a fast idle for 1 min should oil the chain well enouth that it starts spraying off the end of the bar when you gun the engine.

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.

Testimonial: "I think this is excellent advice. Thankyou very much"

Remove the bar and chain. Start the engine and observe the oil delivery port in the side of the engine case. At a fairly fast speed, the oil should ooze out of the port. If little or nothing, check the pump, lines, and in-tank filter. If ok, clean the bar drive-end holes of sawdust and dirt, especially the small passages that go from the large holes out to the chain groove. Clean the entire groove and the outer end sprocket. Reassemble and test the oiling by running the bar tip at speed in front of a piece of cardboard--it should throw off a thin line of oil after several moments. Hope this helps!

The easiest way to test is on the machine. Remove the ignition switch wire from the module coil. Check the pole gaps of the module by inserting a thin business card into the gaps after turning the flywheel magnets under the module. Loosen the module mounting screws to allow the module to contact the magnets, tighten the screws, and turn the flywheel slightly to release the card. Turn the flywheel one full turn to make sure the gaps don't close up further. Use a fresh spark plug gapped at 0.020" and try for spark. If nothing, replace the module. This gets around measuring resistances while trying to evaluate the module. Hope this helps!
