Trigger not working

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 :

Make sure the throttle cable is seated properly inside the handle and rejoin the two halves of the handle back together. The spring returns the trigger back to its normal position once you take your finger off. If the trigger does not return, your spring is broken and needs to be replaced.
If debris or residue from old fuel has entered the fuel filter, it could be so clogged that fresh fuel simply cannot reach the combustion chamber which can prevent your weed eater to start again. If your fuel filter is inside the fuel tank, you will likely need professional service.
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.
Turn on the ignition switch and pull the starting cord quickly. You should see a spark in the plug gap. Since the spark may be faint, it may help to do the test in a dark area. If there is no spark, check for a broken or shorted (bare) lead wire or bad switch.
Whipper snipper engines have a device called a magneto for creating a spark at the plug to ignite the fuel / air mixture in the cylinder. If you don`t get a spark at the plug and have tried a new plug and checked for loose wiring without success, this module may be at fault and need to be replaced.
Check to see if the switch and terminals are free from rust and replace any damaged or broken spark plugs wires as necessary. Alternatively, it could be a bad ignition module. A simple way of testing the ignition module is to leave the car idling for 30 minutes and then tap the ignition module with a screwdriver.
Simply remove the spark plug pour a little oil in through the spark plug hole could be regular motor oil or a little 2-stroke gas mix oil on top of the piston and it will help free it up.
The most common reason for the cord refusing to rewind is a broken or worn out recoil spring. This tiny spring hooks onto the pulley and is stretched out when you pull the cord; when you let go the spring is meant to snap back to its original position.
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.

I just put new fuel line on my trimmer now i cant start it not getting fuel the line never fills with fuel but i can **** fuel out so i know it not pinched it a weedeater brand ght-17
ANSWER : Make sure the little valve under the tank if you have one is fully turned clockwise. Make sure there is nothing clogging the tiny screen inside the fuel tank. Check or test your primer bulb it may be leaky. If carb or intake is leaking, you won’t get gas either. If you have a filter on this model, try changing it.

Have a Husqvarna 41 about 10 years old. Takes a lot of pulling to get it going but once running it woks allright. Lately it will not start and after new gas and plug it starts but when I engage the trigger to start cutting it totally cuts out and I have to pull it many times to get it going again And when I pull on trigger it dies after 20 seconds. Any ideas on what the problem is?
ANSWER : Hi
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of chainsaws.When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.Make sure you are using fresh fuel…and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.If the chainsaw is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.Note:The little spring inside of the carburetor goes under the float arm.That is where your fuel inlet needle/float valve is located…on the arm at the end.Normally there is a small indetion in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.Once you have your carburetor cleaned/rebuilt that should solve your problem.Please take time to rate me

Replaced Poulan 25cc weedeater fuel lines/Now no start
ANSWER : You have/had a fuel filter in the tank.The connector goes to that filter, I think. The length does mean something but I don’t know any way to figure it without a manual. You could try to figure from the total length. The fuel filter hold the line toward the bottom. Good luck.
