Stihl Chain Saw Model 011 not running smoothly and will stop frequently. The chain is not too tight and will turn easily. I replaced the spark plug and put in new gas and ran the saw long enough that only new gas should be left.
I've been messin with my poulan 2150 that was doing the same thing. Good, fresh gas, good spark,etc. I noticed whenever I loosened the fuel cap it would literally spray gas out! alas, I removed the muiffler assy and the darn thing fired up the first pull! I've got the muffler parts soaking in gas right now and I'm sure this the problem. It just makes sense especially if you use the same 'mixed fuel' can for weed eater, blower,etc. Check your's out, it could very well be your problem too! GOOD LUCK

One of the fuel lines turned out to be broken and the fuel filter and air filters were partially stopped up. Since the line was broken I do not know where to put the line that does not go to the filter. I can see one end connects into a nipple at the gas tank. Where does the other end go.
