This is a common problem. The fuel lines can become brittle and fracture, or sometimes they swell and will not stay on their connections. The tube that connects between the carburetor and motor is likely used to pulse the fuel pump that is internal to the carburetor.

The primer pulls the fuel through the carburetor drawing the air out. As the primer is stroked first air than fuel is pumped out of the carburetor. The output of the primer returns to the fuel tank. That fuel line appears to have failed or become disconnected in your craftsman. Either the hose has broken at or near the fuel tank, or has pulled out of the tank.

There is a small hole in the tank for many machines. The hole is smaller(providing a seal) than the tube diameter requiring a minor force to squeeze the tube back in place. Look for the fuel feed tube that also connects from the fuel tank to the carberator. Any loose connections will allow air into the carberator and it will not beable to run. Important is that the fuel feed tube can not be switched with the return tube from the primer. Connected inside the tank is a fuel filter that protects the carberator from contamination.

Hope this helps? Answered on Jun 28, 2017. Hi Pam: Using chain saws takes a bit of getting used to, and it can be DANGEROUS. The chain must be sharp to be able to cut properly, and a sharp chain 'bites' into the wood.

Before you touch the chain into the wood, you have to speed up the engine. This takes some getting used to.

Try this technique: With the chain about an inch above where you want to cut, squeeze the throttle about half way so the chain is spinning. Touch the chain to the wood and increase the engine speed as the chain starts to cut.

The harder you cut, the more power you need to apply. After a while it gets to be second nature. Work Safe, and get an experienced friend to help with some 'hands on' coaching. Cheers. Answered on Nov 26, 2015.
