Homelite 240 chainsaw spiting gas?

Spitting gas is not good. It's probably leaking there instead of going into the carburetor where it can fire the engine. Need to find that leak and change the hose it's running out of. You get gas to the carburetor by gravity and vacumn from the engine. With a broken hose you loose all gravity effects and vacumn that would pull the gas to the carburetor.

Homelites from the beginning of time have spilled mixed gas down over the cylinder head by the spark plug from the gas cap. Then you go out and cut massive amounts of wood and all the sawdust swirls around the head, sticks to the oily gas residue and sooner or later it builds up in the cooling fins surrounding the cylinder head. This causes the chainsaw to run hotter because it can't cool efficiently and the gas tank is right there close to the head and cylinder so it absorbs a lot of extra heat, so much so that i've seen the gas inside the tank literally boiling hot which forces it out of the gas cap vent and spills more oily gas mixture over the head to accummulate more sawdust and cause more overheating. Care should be taken not to overfill the gas tank. Keep the saw and cylinder head clean of buildup so it can run cooler and change gas tank caps often so that you have a clean vent incase you do build up pressure.
