I have a Husqvarna 257 that has good compression and is getting at least some spark, but will not start. Is it possible for it to be out of time?? OR???

The flywheel is held in place with a woodruff key it is possible it slipped but not likely. Did you replace the ignition? Have you tried adding a teaspoon of fuel directly into the carburetor throat? Did it try to start when fuel added? Have you inspected the plug after trying to start? Is it wet? This is a fine saw. It uses the same frame as the 262, one of Husky's best. The operator's manual is complete and detailed. I wish current models were as good, You can reply to my questions below or repost whichever is easiest for you. I hope to hear from you.

Hi

you do not have to set the timing of ignition system because it is electronic(ignition module).If you have compression and the fuel reaches the spark plug change the spark plug with a new one of the same heat range.Start the engine.
