Experienced gardeners share their insights in answering this question :

The air filter is a piece of cake… it is inside the middle cover which comes right off….The fuel filter is a different animal and is located IN the fuel tank at the end of the smaller diameter fuel line which comes out of the tank and goes directly to the body of the carburetor…your problem could be something else entirely though…like worn carb parts…partially clogged muffler and/or arrestor screen or port. These engine produce a by-product of carbon because of the amount of oil they burn along with the gas. It’s good that it at least starts but I am leaning towards a problem with fuel delivery here. Drain the fuel tank… Look inside it and check condition of fuel filter…sometimes they break/rot off of the fuel line in the tank and the fuel lines should ALL be replaced at that point.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

A clogged carburetor is most commonly caused by leaving fuel in the string trimmer for a long period of time. 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 cause the engine to stall.

Remove the air filter and spray carburetor cleaner into the intake. Let it sit for several minutes to help loosen and dissolve varnish. Replace the filter and try starting the trimmer. If this doesn`t solve the problem, consider disassembling the carburetor to give it a more thorough cleaning.

The air filter or exhaust port may be blocked. The trimmer may need lubrication and cooling fins or air passages may be blocked. A cordless trimmer`s battery or charger may be faulty.

If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.

So, an air filter might clog over time. Once blocked with dust and debris, it cannot supply the required amount of oxygen to your trimmer` engine resulting in power loss. Find the air filter, take out this component, clean and reassemble it. Replace the part if you cannot reuse it.

The gas should be 87 octane with no more than 10 percent alcohol. The oil must be formulated for two-cycle engines. Don`t use automobile motor oil because it contains noncombustible additives that will foul the engine.

An air bulb, or primer bulb, on a weed eater forces gasoline into the carburetor to start the engine. Each push of the bulb sprays a fine mist of gasoline along with air needed for starting.

The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the string trimmer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance.

This can be due to corrosion, scratches or general wear. As a result, the cutting edges of the cutter comb of your blades are no longer sharp, reducing their ability to cut. Sharpening the blade is required to reface the cutting surfaces restore these sharp edges.

If the engine is not revving up and cuts out before you reach higher revs then you need to do the following checks: Fuel: Make sure it is fresh and correctly mixed (see `Starting Issues`). Air filter: Make sure it is clean and unclogged. Fuel cap: Make sure it`s hand-tight.

If your trimmer won`t turn on, especially if it has not been used recently, you may simply have a drained battery. Plug your trimmer into your charger and see if anything happens. Ideally your trimmer will recognize it has been connected to a power source and charge its battery.

When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.

One reason why one of these trimmers may die at full throttle is that too much oil is in the gas, which causes poor combustion. Improper operation, including overuse of the choke, can also be responsible. Poor combustion produces carbon deposits that foul the spark plug and exhaust port, making the problem worse.

The most likely culprit is a dirty or clogged air filter. Issues with your fuel pump or fuel filter can also cause your engine to idle then die with any throttle. If you have an older car, it could also be a bad carburetor.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.
