I did not think there was a chance in hell this was going to fix my weed eater. I was just getting ready to buy a new one when I decided to give it a try, 2 seconds with a pen and I'm golden. Thank you very much!

My dad showed me the pen trick also but he would heat the end with a lighter and it makes it fit perfectly. Great video.

I just unscrewed the two screws holding the primer bulb without disconnecting the gas line. Lifted up and saw a dirty screen filter. Took a q-tip to absorb the excess gas which also removed 99% of the dirty particles then used compressed air to blow out the rest. Screwed it back on and cleaned the air filter and now it runs like new. Gotta love KZfaq

Great video, I had this problem and using a bic pen worked. I put on a bunch of new parts for my weed eater and was so pissed I couldn’t get it started. I didn’t want to buy another tool that would take weeks to get here and this worked wonderfully, thanks for the vid!

I did a carb replacement on an older trimmer. The new and original carbs had th SAME issue as shown above. I bought a new trimmer and ran it for 3 or 4 seasons before it started having this issue. battled it for a couple more years as i only used the trimmer 4 or 5 times each season. Played with choke setting (very finicky setting) once I got it started. Finally found this video and fixed the issue in 30 seconds. SO much frustration just washed away! Thank You!

Thank you again for the video, demonstrating how to fix this sort of problem. Of course, I'll give this a try to fix my collection of weed eaters for selling, thank you.

Thanks for the pen tip....after an hour and a half looking on line for ways to adjust screws....finally.....thanks again

That’s the best video I’ve see out of many,I needed to see the tip of the tool,and you made it clear.Also the make shift pen is also great tip.Thank you.

Great idea using the pen👍 I have thrown a couple away after taking all the usable parts off them due to low compression.

Great video. Just used this trick to get my trimmer working.

I was outside all day running in circles… after 3 minutes this got me rolling again… thank you

I have 3 new weed whackers because of this..lol.i literally used a new on 3 times and it started dying when squeezing throttle..

I was given a mid 1980s WeedEater 1400 model in really good shape that would not start. Pull/push only for choke... no bulb at all. I found fuel lines deteriorated and the metering diaphragm needed replacement. The carb is tricky to get out and confounding for an amateur, but the metering diaphragm is easy to feel as a bit stiff and not pliable when exposed. I will install a new one and try again now that new lines and filter and correct fuel mix is ready. Spark plug was decent but replaced. A service shop job would easily be $50-70 and I can do this myself . 2-cycles are not real complex, but you need some understanding and patience... And this guy is methodical and clear as he explains step by step. On a mid 1980s model 1400.... the adjustment screws are marked H, L and are slotted ! So no problem other than a long blade small flat tip driver is needed ... Start at all the way 'in' just lightly and then back out about 1.25 turns each screw and go from there to adjust for smooth and barely rich running at L (idle) and H (full power).

I've ran a Murray weed eater with a OEM carburetor on it and a curve shaft Craftsman weed eater with the same carburetor on it as well and the same thing to another Craftsman weed straight shaft string trimmer

Thanks for the video! Just about to throw out my trimmer, but your help saved the day, and I saved time and money.

I use to use a feather light weed eaters but they don't last me very long but I get my money worth out of them when I use to run them then I ran Bolens weed eaters and I ran Craftsman weed eaters as well and I ran Echo Husqvarna and Stihl

I've got 18 yrs out of two of these weed eater brand W. Eaters and the 2nd is still going strong and it gets used about an hour a week. Replaced fuel lines a few times spark plugs air filter pull string and string head and primers. Basic routine repairs that happen to all after a given time.

Good little fix mate I have a full set and very cheap

I have the same Weedeater I picked out of trash. I ended up using a electrical wire butt connector with needle nose plyers to turn. Adj screws but I also had to replace gas lines .

That’s awesome. Now I know what to do next time, thank you 😌.

In my case, the issue was that the rear main seal, or oil seal was having some loss of compression. I noticed that the bolts that hold the back plastic seal, were loose and needed tightening. In addition, the seal was not seated and the gasket for that seal was as well loose. That solved the issue of a stalling engine for the weed eater.

I was given a weed eater because it would start and die, hope I can get it to run Thanks for the video

I came here to find the location of the adjustment screws and as a bonus got a tip tor the tool, thank you.

I have the same one. I hope you have more videos.

Works. You rock!

Genius. Trying the pen trick.

I just found the same weed eater during big garbage day, brand new! doing the same thing when pressing the gaz, did this, IT WORK! Free weed eater hell yeah

I had big trouble with gas powered , which led me to start buying premixed fuel. I've learned a lot from tearing them up. 😁😁. I hope to successfully repairing one someday. 🤗🤗😂

Back at the end of the '70s I bought my father the weed eater brand weed eater. After it was a couple years old My father every spring would have to take it to the shop to get it worked on and it would last throughout the summer. If I'm not mistaken it lasted close to 20 years before my father went and picked himself up a new one. Touch on what you were saying about the special screwdrivers. If you are a prime member you can get a good set of these specialty screwdrivers for less than $10 and comes with either a bag or a case to put them in. After watching a lot of your videos and some from other KZfaqrs is how I found out that you could adjust the carburetors. I was always told that they're sealed because of the government. Let me say this about the set I purchased from Amazon. For the price the quality of those screwdrivers is unbelievable. I can honestly say I don't know how they are able to stay in business selling them at such a ridiculous price. My only complaint was with packaging. Every one of the screwdrivers which I purchased the 10 pack were all wrapped up in individual little baggies. I felt as far as the environment and recycling that was a little too much. I know that they don't want them banging against one another in transit but I would say they could come up with something better. I had a nice little pile of plastic once I filled up my case. Like always I did enjoy your video and as always I made sure to hit the like button. Look forward to watching another video.

Nice tip to use a pen. I had not seen that before. Good job brother.

Thanks for the great video. Unfortunately mine will run just fine but dies out of nowhere after a couple minutes then starts right back up and dies again after another couple minutes.

It worked! Thank you!

Nice idea. Most weed whackers I work on have the old walbro carbs that have 1 flathead adjustment screw . Why they changed it I don't understand.

Finally found a fix with this video. Thank you!!

Genius. Worked like a charm.

Pen trick is pretty cool. Thanks.

I call them bic lighters because when they run out of gas, you cannot get them to ever run right again. Generally after a few years the fuel lines rot and fall off. I pick them up all the time and fix them up. For a few dollars I can replace the lines , then resell then.

I have a Ryobi and this is recently the problem I had with it after switching the bubble.

I was just given a poulan P1500 in really good shape. It just needs a rebuild kit wich cost 35$ and it will be like new again.

Awesome thanks I'll try it

Hey man I just learned something a big thumbs to you I will remember that one

I have a carburetor off a trashpicked weedwacker with a dead ignition system. The bic pen didn't _quite_ work, but the larger "gamebit" bit in my chinese screwdriver set worked a bit better.

I wish mine had the exposed screws like this one. It has a Walbro barrel style newer carb. The high speed is buried under the primer bulb and takes a “micro d” tool that I was very lucky to find. The low speed is on top of the barrel like usual but I almost didn’t see it because it is very small and just looked like a brass plug.

You can use a piece of fuel line for the same bodge. It's tricky but will get you out of a pinch

I jave two trimmers one which wont start. The other has the same issue you had. I bet this will fix both. I ordered a $10 toolkit off amazon. I’’m post another comment after.

Or you clean the spark arrestor if that doesn't work and adjust the carb if that doesn't work throw in the trash because it will need a carb you can check amazon

FML I recently got rid off mine an it was doing the same now I have a homelite straight shaft that I'm semi rebuilding off to Bunnings tomorrow new primer bulb sparkerlater plug an grease an then will have a new best hahah

This is a awesome tip fixed mine in about 10 minutes thanks

Yes someone did and I got the weed eater off side the road and it ran

This is a small world when we look at it. Here is a crazy story. That machine is old as dirt. So happens 4 days ago guy next door put exact one in trash. Said he brought a Bolens curved shaft ( junk ), at Walmart. Said thing all at onece started and dies ( old machine ). Well, not that I need more projects or junk, but I took it lol. 2 days later returned it. Says what is this. I said a working weedeater. One pull fires up and runs. Verdict- course people in their bad gas. Lines all white and carb clogged. Now I did ajust carb first ( with the tool because much easy way to do it ). And that brung it back to life. However, I suspected more to the story is why it acted up. So I rebuilt carb and changed them nasty lines. Any event yes, the pen trick is where I started. That got old and got tool. Good vid.

Works awesome cheers

I picked up a basically new looking ryobi that runs but dies. Paid $5 . Using your lesson to adjust it tomorrow

Same as a Stihl dolmar

Yes I’ve thrown out several because they wouldn’t run. Now after watching this video I regret it. I almost threw out a Stihl but I’m glad I didn’t. After a few adjustments it’s going strong.

Thanks for your help I have same issue in effco hedge trimmer TG2650xp Very difficult adjustment urgent make video for this brand 🙏

I was skeptical about the pen use. But my wife "donated" a Bic. I slightly ground down the side of the plastic pen tube to fit easier into the carb. Unbelievable - I now runs excellent after about half a turn on both. Frustration GONE!

Great info. Question, can a bad coil stop the engine from powering up.?? Is not advancing.. ?? Same symptoms.. No adjustment on these carbs. Can get to low, not the High. Thinking coil is not advancing. What ya know. ??

Never t6hrew anything away but maybe gave away after a fix and the pen is a GOOD idea! Blessings

Now there is a useful hack!

The Featherlite is a great weedeater, - they are Poulan - Husqvarna based if you trace back far enough, and a very good performer. I have 2 here in New Zealand. One of them is having the exact symptons as on this video and I have tried this same procedure as well as clean spark arrestor but makes no difference. Will try a carb kit next, although carb looks good inside.

Use an exacto knife to trim the inside of the pen for a better fit.

Many thanks bro

Working on tuning up an FL25C right now. CanadianTire sells fuel lines in a kit but I need to go back and get another 8" or so of 3/16" (the 1/8" isn't tight enough for the primer-bubble return line back into the gas tank. I'll definitely be trying the Bic Pen adjustment as I don't have the splined tool you refer to. Thanks and will let you know if I can get it working again.

I trash pick trimmers, replace the rotten fuel lines and rebuild the carburetors and scavange parts off them. I've been running the same trimmer for 30 years now, lol.

Saw this right after ordering the tool lol

Wouldn't though it away l would fix it and enjoying your videos

Pretty much the same symptom is a broken gas line in the tank .I would try to pick up the screen first look to see if the line didn't rot off if the lines are Ok then by all means adjust the carb but it your putting 87 ethanol gas in it chances are the gas lines are shot

Thank you for the video !! Can turning the L screw too much make it run lean ??

awesome tip.

Yes I have

Awesome video and informative. What does the black pin carburetor screw adjust? Thank you

I tried adjusting the carb screws-didn't help! Took the carb apart and inspected, blew it out-didn't help! Put in a new spark plug-didn't help much! Are there points and condenser on this model of weedeater?

I have this same trimmer it will idol whith the choke on and will not take eney fuel only idol put when you take the joke off it shuts of completely.what can I do I have 4 of these that different folks gave me pretty much same problem.all help would sure be appreciated

Thanks dor the video man! Mine kinda do the same thing but mine idles and if I go slowly with the trigger it works but if I do it fast it dies

Hey can u help me to adjust the valve on a cub cadet push mower 173cc /6.76 ft-lbs OHV thanks

My last 2 new ones out of the box I had trouble with...one or two uses and the same schit...going back to electrics and buying a new one if it pukes on me....I Think thats the whole industry...my first weed eater from Menards lasted 8 years....the ethanol in fuel should be outlawed....tried making my own e-free gas but it got real messy and lots of byproduct. The ready mix fuel was about 7 bucks a quart then...not sure what it costs now...

Yes I had 2 brand new troy-built trimmers that I could not get running through one away and gave the other one away

I wonder if the access vibration would cause the L and H screws to move slightly. Most cases is that true?

The idea is good, but you don't show which screw you are adjusting, what direction you turned it or how much

I have a echo gt225 weed eater and the bulb won't suck in gas can the plastic white peace be bad

I’m about to throw away 2 trimmers because of this problem. I hope it works 😩 if not I got to go buy a new one ((again))

I have the same set of those carburator adjustment tools great video thanks

bought one for $20 yesterday with this issue, husband thinks carb is dirty though, my daughter will try to fix it

No but want to use my featherlite as a outboard for my mini boat....can I add a clutch and what kind to my featherlite...

This is the same problem I'm having with my chainsaw. It idles fine but doesn't rev. I'll screw with the carb when the parts I ordered come in

What needs done if you have to keep it at full throttle or it will die?

I have the exact opposite problem with my weed eater could this fix that too

I feel like such an idiot now I threw one away because of that exact reason

I have a weed eater every time I use it It dies after 10 -15 mins.and the motor is so hot can see smoke in spark plug,Thats why I can’t finish my lawn.

I'd like to find how to make the string recoil???

This machine looks just like my mcculloch but different color,mine has on/off switch above the throttle lever,i've heard that mcculloch arent very good ? & most ppl say theyr'e crap,never had any problems with it so far 😊😊

I never throw away any I dissect it thoroughly

Why the custom screw head anyway? Prevent idiots (example: me) from screwing the adjusts up?

Does that Brand trimmers head always spin? I have one I’m repairing and before I rip the clutch apart I wanted to see, it sounded like in the video the head on this one was constantly spinning too

I've thrown out a trimmer for looking at me the wrong way.

had this problem , along with fuel issue. seems to run out of fuel. checked lines ,ok replaced carb, ran better, adjusted mixture screws, and started to act the same way as it did befor I replaced the carb, what did I do wrong??

Hi can you plz tell me where I can buy parts in South Africa in Pretoria for my sthil bush cutter I need piston ring and carburetor gasket

Mine has seized any suggestions on how to unseize it.?

It uses gasoline or gasoline + oil ? thanks u

I have a trimmer with a walbro carb..After running for 20 mins or so the adjusting screws vibrate inwards..then starts to bog down..then a quarter turn out on both screws and its fine again for about another 20 mins of run time, until they vibrate in again..I've been carrying the adjuster tool with me..any ideas on a correction? or than a carb change?Thanks
