You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You don’t have to bend up the electrode. HTH

If the spark plug wire goes through a shroud then check for chaffing. I have had a few gas powered tools that just stoped working after running years without a problem. Usually the symptoms of a bad wire (could be Magneto but more than likely it's the wire)is you don't even get a pop while trying to start it

I have a Rancher 55 18" with a new chain. Started


First thing you need to check is the cylinder.Take the spark plug ouy.use a flashlight and look down the hole towards the muffler side.If its scratched up afraid the motor is shot and will need to be rebuilt.If its not scratched up let me know on here.Then I will give you more things to check.

Will not start. Spark ok tried with started fluid


Spark should be blue and snappy with fresh plug gapped at 0.020. Try putting some fresh fuel mix into the plug hole and try to start--it should pop several times. Does the engine seem to have good compression? If not, remove the muffler and check the piston skirt and cylinder wall for severe scoring. If it is, then the engine has probably be run on straight gasoline or poorly pre-mixed fuel/oil. At the very lean fuel/oil ratios ( 50:1) recommended for today's saws, proper premixing of fresh fuel and a modern synthetic oil made for saw use is imperative plus the fuel container should be vigorously shaken just before each filling. If the compression appears good, then check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for any decay or other damage. Make sure the carburetor fasteners are tight. Hope some of this helps!

Husky 55 rancher - I rebuilt this saw but now it won't start. Seems like not getting enough gas. What should I check for?


Check for plugged fuel filter and muffler. Check the fuel lines for decay or damage. Did you service the carburetor? Make sure the lower chamber diaphragm is not hard or cracked. Did you change the two jet settings? Put some fuel mix into the plug hole and pull it through--you should get a pop or two. If ok, then concentrate on the fuel problem. If no spark at the plug, check the ignition module gap to the flywheel magnets using a thin business card for a gauge. Hope this helps!

I have a husqvarna 455 rancher. It was working


Take it right back to repair shop and have them fix under their warranty.

It is possible the fuel hasn't got to the carbureator due to plugged fuel filter or fuel finder OR an air leak in the fuel hose.

Describe your Husqvarna "Chain Saw -


Remove the spark plug and test for spark. If ok, try some starting fluid in the plug hole, install the plug, and try to start. If it runs a short time, it is not getting fuel. Check fuel lines including inside the tank. Clean or replace the air filter. If this saw is fairly old, the carburetor probably needs a re-kit and cleaning. Does it have good compression? Check the muffler for plugging. Make sure the fuel/oil mix is fresh. Good luck!

350 HUSQVARNA HAS SPARK WON'T START


Clean air filter and try starting fluid through air intake if you have spark this will definetely start it......On the rancher , is the air cleaner clean??? Remember that all you need to make an engine run is fuel , air , and an ignition source .. When you attempted to start the Husqavrna by adding fuel to spark plug chamber this actually causes a no start or very hard start condition it will act like if flooded....What does help if you remove the spark plug pull the pullstart and ensure that no liquid (gas is coming out of chamber) if it is keep pulling until it does not.... then take your spark plug ,after you have cleaned and gapped it, and with a butane lighter heat the tip for approximately 30 seconds and then reinstall plug and give it a yank after you spray starting fluid in the air intake....Good Luck
