Today is Saturday June 27, 2009 so this is probably too late to help in this case, but I didn't see anyone with the correct solution to this problem, so here is what I found. This is the same problem I had, open the carb area and see fuel line crumbled and don't really know where everything went. In the pictures, the barrel fuel line should go to the fitting at the carb intake, in the picture it is going to the top where the impulse line should go. The flapper valve should have a short piece of line sticking out with a duck bill (check valve) and nothing else. Looks funny, but that is it. The line that goes to the top of the carb is the impulse line and goes to a nipple on the base of the cylinder. You feed the line through a slot in the plastic housing below the carb, through to the barrel. I took the starter cover off and used a needle nose pliers to shove on the fuel line. I rebuilt my carb twice and was going to buy a new one, but went to the local saw shop and the guy laughed and told me to bring it in and he would tell me what I did wrong... and he was right. You think the two lines coming out of the tank go to the side and top, but that's only half right. Sure enough, when I got home, I took the starter cover off and saw the nipple on the barrel with rotten piece of line on it going nowhere. There you have it. I had almost given up on this saw and had my wife buy me a new one last Christmas and there the 3300 sat, but I couldn't bare to give up on it because I don't use it that much and it was nearly new. Hope someone gets use out of this, but I had to tell someone!
