Yes, that is a normal occurance, however, all saws have to have a way to relieve that pressure. Many tanks have vents on top, others have fuel caps that vent. Both should be inspected for being plugged with saw dust, or rubber components that have become damaged over time.

My Echo CS 3400 chain saw has an air vent problem


Most handheld power tools have a tank vent that will hold some pressure, Don't quote me. But If I turn the saw sideways and the vent allowed fuel to drain out THIS WOULD CREATE A FIRE HAZARD. If the fuel is boiling when you open the fuel cap could this be a engine temperature problem? or low octane fuel.

How to conect fuel lines to poulan chain saw 2375 Le


The hose coming from the fuel tank with the filter on the end goes to the fuel inlet on the carb, this is the conection closest to the alloy pump cover held with a single screw, now take a hose from the other conection on the carb to the shorter ( suction side ) conection on the back of the primer, take a hose from the longer conection ( pressure side ) on the primer back to tank, this just pushes into the tank, just remember that the primer pulls fuel from the carb and dumps it back to tank.

Attempting to replace fuel lines on a Poulan 2550 Chain Saw. I need a detailed explanation of which lines go to which ports. Two different size fuel lines. It appears big one goes to the filter in the...


The size of the fuel line doesn't really matter if either one will fit on either port on the carburetor. When you pump the primer put a finger on one of the ports. If the primer goes flat but does not fill back up, you need to hook the fuel line with the fuel filter on it to this port. If you pump the primer and the unit will not go flat unless you remove your finger, you need to hook up the fuel line that just returns the fuel to the fuel tank. Make sure that no fuel will leak if the fuel tank is pressured up. To check just shake the saw a couple of times. This will build up pressure within the fuel tank, you should be able to tell if the tank will leak quickly. Best of luck.

Oil leaks out of the remington electric pole saw. The saw is stored/seated upright and I can't see the problem


Remove the bar and chain, then clean the entire area. Look for leakage at either the small port where the bar fits, or from the motor case itself. Make sure the oil tank vent is open so that pressure doesn't build up from heat. If the leakage is from the case, then look for a crack in the oil tank, or a defective oil line from the tank to the oil pump. Clean the drive end of the bar oil-channels that go out from the large holes to the chain groove on each side. Clean the entire chain groove. It also may be easier to just dump the oil out of the tank after each use if the chain seems to oiling properly. Hope this helps!

Saw runs great for the first few mins and then looses power like I'am losing fuel let it sit and it will run great and then the same thing happens


Check the vent in your gas tank cap. It might be clogged. See if there is pressure in your tank when the saw looses power. Some saws are great for getting hot and heating up the fuel tank and building up pressure when the fuel cap vent becomes clogged. When people fill their tanks and overflow fuel leaks down over the engine, the oil in the fuel mixture tends to coat the engine and then saw dust sticks to it. Over time it clogs up the fins on the cylinder head and makes it harder for them to stay cool. The increased heat can add to the problem I spoke about above. When you build up that pressure in the tank it tends to force extra fuel through the carburetor and makes the engine run rich.

  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.
Take lots of notes and a few digital photographs to help with reassembly. HTH

I try to start the dx3300 chain saw but not start look like fuel isn't go to spark


No-fuel problems are the result of bad fuel lines from inside the fuel tank out to the carburetor. If lines look good, rebuild the carburetor itself to repair hard, cracked diaphragms and varnish build-up. If carburetor is a Walbro brand, go to: www.drystacked.com for a 12 page PDF on theory and repair. Good stuff!

Homelite 42cc, 18" bar chain saw - Engine will not restart after saw has been used for a while. Wait overnight and it starts fine.


After it has been used for a while and it won't restart, try loosing the cap to the gas tank and see if there is pressure escaping. The homelites are notorious for the vent screen in the gas tank cap getting dirty and pressuring up which forces more fuel into the carburetor and floods the motor. This is also aided by spilled mixed gas which has oil in it running down onto the cylinder heads and then the sawdust sticks to it over time and building up where it makes it difficult for the cylinder head to get rid of all the heat it makes from running. This in turn makes the gas tank hotter and makes it build up pressure in the tank. If the vent cap cant get rid of it as fast as it is created the increased pressure forces too much gasoline into the carburetor and it floods it out.
