I bought the same Chain Saw in mid 2007 in 2009 I stoped to refuel and could not get it started. After checking out the IGNITION ASS'Y THEIR IS NO SPARK AT THE SPARK PLUG. Ordered a replacment after a weak after calling them back they no longer can get the part or a substitute from the company. The barcode on my saw says it wes ASSENBLED IN TIAWN. So here I have a saw with 10 hrs on it that will not run. Need help
