Husqvarna 480 Chainsaw CD, will not start

Hello.

Husqvarna 480 Chainsaw CD, will not start

Good spark, the fuel reaches the spark plug.
Spark wet.
Last year worked well and now not.
Throughout the year does not work.
Anyone have same problem with this machine that can guide me.
thanks

Is the fuel fresh or old?
I'd try a new plug before anything else.

You say throughout the year, meaning the saw has done this before? What was the overall running condition prior? Good point on the fuel age could be a key. You may also have a fuel line issue hole in it maybe, or may be a carb issue, and need a carb kit. But like Arrowhead said swap plug, and fresh fuel to start with.

"Good Spark" but is it good under compression? CHange plug first, make sure properly gapped. Maybe bad coil.

BTW.... how is ompression? Did you pull the muffler and look to see if the piston is scored?

If the plug is wet you prob have it flooded, pull plug, check for spark , if ok set plug aside and flip saw over and pull around 50 times :hmm3grin2orange:to blow out fuel, reinstall plug and try again, if it floods again then you have a stuck metering needle and you will then need to get in the carb.

All year old fuel.
Now fresh fuel.
Piston-cylinder does not appear scratched.
Now it has less compression than the past year.
When was OK
