Re: Poulan problem/question

>Terry, the reason the saw speeds up and goes like it should right before it runs out of gas is because it is leaning out at that point. Actually, it is not a good idea to run any 2 cycle Engine completely out of fuel. When they run out of fuel at high RPM's, they are starving for lubrication, which will shortnen the life span of the Engine. It the limiters on the High and Low Speed adjustment screws on the Carb. are Plastic, you can sometimes just pry them off. Some manufacturers install these to keep folks from messing with the fuel mixture, and leaning it out too far, and blowing it up. Somewhere in the manual, it may tell you the starting point for adjusting the carb from scratch. If not, I would be that if you can remove the limiters, then GENTLY seat the high and low speed screws on the Carb, and then back them both out 1 1/4 turns, that will give you a place to start tuning the carb from. Most saw carbs are pretty much the same in this regard. If that doesn't do the trick, I would return it to the place of purchase and let them service the thing to your satisfaction. If they see that you have messed with it at a later date under warranty, they may give you some grief over it. I have only owned Stihl Saws, so I am not real familiar with the new Poulan Saws, but I have worked on many of them for friends. Clean the Air Filter, stick in a new Plug, see what you can do with the Carb, and as a last resort, take it in for service. (One other thing I have found over the years is that Champion Spark Plugs are junk for Chainsaws.........get a NGK or Bosch Plug for it, they are MUCH better for Chainsaws.) Let me know what you find Terry............there is nothing worse than a persnickity Chainsaw!
