I need a fuel line routing scematic for a craftsman 42cc chainsaw

Customer Question

I need a fuel line routing scematic for a craftsman 42cc chainsaw with a Walbro carburetor, model numberNNN-NN-NNNN I replaced the lines and now it hardly starts, won't run normally, or accellerate and stalls out. Line routing is the only thing I can think of that may have changed. I thought I did it correctly. Everything else seems normal. Can you help me? By the way, this is the same question I asked last nite, so please ignore last nite's question. Also, I may be away from the computer working on the chainsaw, not ignoring you. Thanx.

Not only was the answer too late. But the info was wrong. My problem was indeed the fuel line routing. Fortunately, I found a friend that had one like mine and I copied his. Now it runs great. Thanx anyway.
