While draining the fuel tank may sound like a good idea, it could harm your engine. Running a lawn mower dry will make it harder for it to fire right up when it comes time to take it out of storage. This is true of all your outdoor equipment and tools, from mowers and blowers to trimmers and chainsaws.
Slide the small end of the funnel into the open housing on your lawn mower engine. Pour 1 tsp. of gasoline into the funnel. Let the fluid run through the section of pantyhose, through the funnel and into the engine.
How long can gas sit in a lawn mower? Depending on the gasoline formula it can degrade in as little of 30 days. Properly treated gasoline can stay good for up to a year. To prevent this from happening, you have two choices: empty the gas tank or add a fuel stabilizer.
There may be old or bad fuel in the carburetor float bowl. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner.
One of the easiest ways to maintain your lawn mower for seasons to come is by using a good quality fuel treatment like STA-BIL®. It`s the official gas additive of all Briggs & Stratton® engines. Fuel begins to degrade in as little as 30 days.
Bad Gas in Your Lawnmower? Here`s How to Fix It. If you neglected to add gasoline stabilizer to the fuel prior to storage, empty the tank and replace with fresh gas. If the tank is nearly empty, simply topping off with fresh gas is often enough to get it started.
This would cause the engine to stumble. To address this most carburetors employ what`s called an accelerator pump, which is essentially a gasoline squirt gun that shoots fuel into the throat of the carburetor to enrich the air-fuel mixture in the brief moment before engine vacuum returns.
Components of carburetors usually include a storage chamber for liquid fuel, a choke, an idling (or slow-running) jet, a main jet, a venturi-shaped air-flow restriction, and an accelerator pump. The quantity of fuel in the storage chamber is controlled by a valve actuated by a float.
Gasoline has a shelf life of just 3 to 6 months. Over time, bad gas can gum up your mower`s engine. Siphon out the old fuel from the tank to get rid of bad gas.
Step 1: Empty the gas tank
Unused gas left in a mower over the winter can get stale, gumming up the carburetor and inviting rust. First, add fuel stabilizer to the tank, then run the mower to distribute it through the system. Turn the mower off and allow the engine to cool, then siphon excess gas into a clean can.
Step 1: Drain The Gasoline
The Ethanol in your gasoline is also corrosive and can damage the carburetor. To keep your lawn mower in good shape over the winter, you need to drain the gas. Note: We`ve found that fuel stabilizers do NOT work at preserving fuel over the winter.

I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?

My Poulan will start up but then when I try and give it more throttle it dies or even when I let off the throttle to idle it will die. Is this fuel line o dos the carb. need to be cleaned? How do I access these parts if so. New to fixing a chainsaw.Thanks!
It sounds very like a fuel issue, before diving into remove the carb check the easy stuff first, drain the fuel tank and fill with fresh fuel, pull the fuel hose out and check the condition of the filter on the end,any doubt replace it, check the condition of the fuel hose up to the carb for cracks or signs of age. Let us know how you get on
Poulan chainsaw 18″ 42 cc, pro gas filler cap?
Yep they swell after a while and will not screw in or out!
Sand the threads down so that the circumference is reduced with a course file or plumbers cloth, chamfer the threads a bit on the edges. A new one will do the same thing after a while so just fix the one you have.

Replaceing fuel line in polan 3300 chain saw – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
Use a piece of wire and insert it into the fuel line, then bend a hook in the end and hook it over the end of the fuel line…lubricate the fuel line with some vaseoline very lightly…about the first one inch of the fuel line and then use your fingers to start the fuel line into the tank, once you have the fuel line in the tank give enough to hook the fuel filter to and so it can be dropped back into the tank.
Below is a drawing of how to route the fuel lines.

The saw starts up fine, runs fine but not for long. it runs for about 1 minute and dies. like it is out of fuel or sucking air, i noticed there is no filter on the suction line and there is another nipple entering the fuel tank which appears to need a hose on it , is this just a return line, or should the long line in side the tank press on to this nipple? thanks,
I’ve had my pp4218 for about 2 years and the fuel lines have rotted. I’m thinging from ethanol in the gas. However, I’m replacing them and cannot tell which lines go where. Does the large line from the bubble go to the filter and the little line return?
