"I received the saw and it seemed, "heavy duty". I installed the bar and chain and fueled it up with some 40:1 mix, gave it a yank and it did not even try to start, i tugged on this thing about 100 times when i finally gave up. so i pulled the plug out "this is not very user friendly" checked for spark and realized i had none, i had to practically dismantle the saw to figure out the problem. 2 yellow wires that attach to the on/off switch were disconnected? after re-connecting them and re-assembling the saw it fired up on the first pull. This Efco is no Stihl thats for sure, i would not buy another one just do to its unfriendly build and so-so power it has............"
