My Craftsman chainsaw let me down again yesterday. Once again, it would start, but would die as soon as I tried to rev it up. Here's the link to my post about this last time: https://www.hearth.com/econtent/index.php/forums/viewthread/13438/ I changed the spark plug, and dusted off the air filter, and still had problems. I then thoroughly washed the air filter, and was finally, after many tries, to get it working again. That is, I'd start i up, then use the choke to get the RPMs up, and finally, I could squeeze the trigger without it dying. I used it to cut a full truckload of 18 inch diameter pine, and it worked OK, but I'm not sure it was providing max power. Today I will do some experimenting (like put in the old plug) to see if I can determine what the problem is. Here's a specific question: I get the impression that just dusting off the foam air filter doesn't help much, but thoroughly cleaning it with soap and water does help. Does that sound right? In any case, if I can get this working well, I'm going to sell it (with full disclosure), and buy a Husky or Stihl. I need a saw that's ready to go at a moment's notice so that I can take advantage of scrounge score.
