I have a friend that bought a new Husqvarna 235 chainsaw from Lowes. He was using it on its first tank when it died. He gave it to me to repair and I can't really figure it out. The piston and bore look good, compression is good. It is getting fuel but it won't fire even once! I have used different spark plugs but it still won't fire. I turned the crank with the plug out and it is sparking. My thoughts are that the ignition coil is not sending out a hot enough spark, but I can't say for sure. Do ya'll have any suggestions/problems like this? Thanks.
