I had the same problem with my new 445. It would not start even with starting fluid. I let it sit overnight, dried off the plug.
Set the choke to on, pull one time. If it coughs, turn off the choke. Mine started the next pull. It seems to flood easily.
Hi Scott
Thanks for contacting the Answer Army to post your questions.
If there are no big elevation differences with where the saw is being used, and the dealer who is not having trouble getting the unit started, I would want to know what the dealer is doing differently that what the end user is doing to get the unit running. Starting fluid is not recommended for two stroke engines since they don't have any lubricating qualities, so that could actually damage the engine if used. If you are following the starting instructions that were included with the unit, there shouldn't' be any problems with starting the saw. If the unit is flooding, it is probably due to leaving the choke on for to many pulls after the unit tries to fire. You should only have to let it fire once with the choke on and then pull it back to half choke for the next pull, or turn the choke completely off to start the engine. As long as you are not in a cold climate, the normal operating procedures should work. If you are in a colder climate, the unit should be warmed up on half choke per the owners manual operating instructions.
Thanks again from the Husqvarna Technical Services Team
