- How to Diagnose & Fix a 2 Cycle Trimmer that Only Runs on Choke. You need to see this!
This trimmer is almost brand new and the landscaping company ruined the engine by running straight gas (no 2 cycle oil mix) in the engine. They had to replace the engine and after doing that it would only run on choke. They couldn't figure out what the problem was and asked me to take a look at it. I found 2 common problems for the reason it would only run on choke.
If you have a 2 cycle engine that will only run with the choke on, I think this video will help you diagnose and repair that problem.

Have a landscaping business and switched to battery powered trimmers because got tired of the piss poor overpriced crappy 2 strokes breaking down. It was a wise investment because I saved time and money
You are a genius. I have about eight weedeaters people gave me that only run on choke. I tried so many different solutions and never even thought about the tank vent. Thank you so much now I have to look at eight of them again LOL😂
Glad I could help
I watched this last night .. I couldn't sleep .. kirk.. I had to go in the garage and work 😅
I have 1 doing the same thing. I changed the plunger because it was leaking then the line was crack so I change it after that it won't run. I will be checking it out again.
You've just help extend the life of thousands of small engines.
This may seem common sense but the way you methodically you troubleshoot is super satisfying and really awesome to see.
Good job.
That's what I call a real mechanic.
I’ve been fighting sluggish equipment, replacing plugs and rebuilding carbs etc. I never ever would have expected the gas tank vents to be the problem. I can’t wait to give this a try.
I had the exact same problem with my echo polesaw/weed eater and took it back to the dealer I bought it from. They installed a new carburetor. I got it home and it would not run. I drilled a tiny hole in my gas cap to get it to run. Thanks for the info.
Today I was adjusting the carb on a weed eater for quite some minutes and realized it was just out of gasssss…
It’s really a problem and I change them as part of the repairs
Guess I should tell people I replaced it so they will know
@@Loavictorit happens brother! I’ve done it a thousand times man!
Looks like the sort of thing that happens to me every year preparing for bushfire season, and every year I take it in for a service. You've just saved me a ton of money and heaps of time waiting. Thank you!
I really like the part about the open flame and gasoline!!
Ok, you are the ONLY one that addressed the crossed fuel lines....which was my problem. Thank you so much for the walk-through. +1 subscriber.
Haha right crossed fuel lines I never looked at that
Great video! Start with the simple stuff and move on up! Crossed fuel lines, I wonder how many people paid for a fix like that! Thanks for your time and sharing! 👍😎✌️🇺🇸
I've had my Roybi for just over a year now and it's doing the same thing this was. I've never taken the lines off, so I know it's not that, so gonna try the filter and see if that's it.
Thanks so much for ALL the tips!! It's great when I can watch a video that actually helps!
Glad I can help... wishing you the best
That was worth 15 minutes. Learned something new. Thanks!
Glad to hear it!
That's the happiness you feel when we start something running thanks for the video
Excellent explanation on how the fuel lines work!! Thank you!
Glad it was helpful!
Be blessed for sharing quietly wisdom. 🙏😊
Thank you and God bless you!
Thanks. I picked up one that was doing the same thing. The fuel cap wasn't venting good and I think it caused the primer button to vapor lock. Cleaned the fuel cap up and unplug the line between the carburetor and timer button and had to pump the primer button a few times to get the air out and now it runs great. Thanks for sharing the knowledge
I like that you showed the trouble shooting steps to finding the problem.
I agree: step by step 101 instruction is masterful! Thanks a bunch!
Glad I could help
Boy how simple you make things, would not have even thought about a mix up in the fuel and return line, great help to start sorting out my problem with my Ryobi weed eater, just replaced the carbie but wont run without choke, now know where to start looking, just hope i have the same problem. also didn't know how to tune the carbie but now have an idea, knew about the small adjustment screw in the top of the throttle body but wasn't sure what it adjusted. Thanks heap, am now going to watch your other videos.
I suppose the reason for higher octane fuel is that it has no alcohol in it that would destroy seals in the fuel system. I have two weed eaters that are 5 years old & they have used regular pump gas since day one. Dunno. Great video.
Arrrrr the joy of finding the problem I know it well, sometimes I'm not so lucky but with the help of people like your self we have a better chance. Thanks from Graeme in Australia
Thanks for the visit
Outstanding! Based on this video I compared our trimmer that starts but won't keep running with the one that is o.k. and darn if the fuel lines weren't crossed! Thank you so much! Glad I didn't have to try all the other things but I WILL remember them!
I have 2 weedeaters and each one has a similar opposite problem you described. Thanks for sharing your experience. I know what to look at now. 👍🏽
One thing that I can hear is that the idle is too high! The first thing that you want to do to a 2-stroke engine is stop the trimmer head from spinning or if it is a chainsaw you need to turn the idle down until the chain stops spinning! When you have a high idle setting your already in to the off idle circuit! And that causes a dead spot when you clobber the throttle! That throttle plate needs to be closed to where if you look inside the throttle bore on the same side that the high and low jet is on you will see two little holes! One on the front side of the throttle plate is direct vacuum and is your low speed and if you crack open the throttle plate you will see another hole on the back side and that is your metered vacuum and opens the high speed.The throttle plate needs to be closed until it is in the middle of these two little holes in order to have transfer from low to high vacuum signal. 😉
He was trying to get it started bro...and keep it running. I’ll bet he knows exactly how to set the idle on a trimmer or other fuel powered engine.
How about a 2 stroke tiller bolens bl410 model it runs and idles on level 1 but when I move to 2 it turns off has a new carb good compression new spark plug good spark
😅
High idle can also be from an air leak after the carb.
Tony Sir! Thank you for this man!! This is something new to me that I did not know and I’ll bet money that’s what’s wrong with mine!!
I’m good on my dirt bike 4T motors, carb or fuel injection or even 2T race motors.
LOL, I didn’t expect to learn here, but sure enough, I did.
Thanks
Thank You .. I think this may actually resolve the issues with my GT200.
Your tutorials are very well executed, coupled with your high energy personality. A delight to watch! Thank you with gratitude from New Rochelle N.Y.
Thank you…I appreciate your kind feedback
There's a whole lot of really good info here about how to troubleshoot different issues. Very nice job.
Thanks
You're friggin wizard! I love your patience and thoroughness. What an amazing video. I just subbed, liked, and saved with this one video. Thank you for being so generous to share your wisdom.
Thank you and welcome
Awesome information. I have a leaf blower and a weed eater acting up. won't throttle or run without choke Awesome!!
Had same issue on SRM 280T. After porting exhaust, replacing carb, filters, and lines it was the two intake bolts that had loosened over 10 years of use(vacuum leak). Thank you for this informative video
Interesting!
You are amazing I wouldn’t have never thought to do this my weedeater has been running just like you described in this video thank you so much
Glad I could help
Thanks. Now I know what else to look for. Huge help.
Same issue for the last 3 yes thank you for the fix
Thanks, my strimmer has only run on choke since new, I'll check it next chance I get, with your video to help me.
mine too.
let us know how it turns out
Strimmer!
Going to get to work and fix mine too ! Thanks for the video !
Glad to help
Great video. Ill try the vent cap on one of mine that was used in really dirty conditions.
Best repair/adjustment video ever. Thank you so much. 👍
Wow, thanks!
Thank you for the video! I was having this same problem with the weed eater and blew out the fuel lines and it ran like a top!
Great to hear
Excellent job! Two very valuable pointers. Thank you.
Glad it was helpful!
I fixed small engine equipment in the past and now do it on the side for fun. One note about that echo brand is they use a hose and vent system...so the gas cap is not vented...thats the difference...like a mower gas cap is vented....and some chainsaws too...on a trimmer you may turn it sideways or upside down so im guessing they made it that way so no gas will ever come out of your gas cap.
Awesome 👌 job thanks my friend. You just fixed my weed trimmer for me. Thank you!
Glad to year that
SIR, you are a great little mechanic. I really wish I could do half as much as you can do. Ive never been able to work on my cars like I wanted to so I always had to buy cars in fantastic shape so I dont have to pay huge charges like so many idiots like me end up. I have been very blessed in the cars ive owned. I have a 2011 POLICE Crown Victoria that had a 109,000 on it when I bought it. It was Fleet maintained by the dept motor pool and it was in perfect condition my mechanic asked me if it was the original motor because it was in such beautiful condition. Anyway Im so impressed with your ability the way you got right to the problem. Congratulation on your channel. I wish you were my personal mechanic. I would trust you completely.
Thank you for your kind words.
This worked! Thanks.
I had the same problem and the fuel and return was also reversed ,and Yes I did it tweaked the high jet an it runs good again thank you
Hello 👋 my name is joe I learned so much from your video you are a great teacher 👨🏫 have a great weekend 😊
Thank you! You too!
The excitement when you fix something!
Love your trick to test lines… Thank you!
Thanks for your visit
covered it pretty well. now I'm going to try and apply to my line trimmer.
You can do it!
@@helpinguonline haven't gotten it yet. I'm going to try again.
Awesome troubleshooting!
Thank you, my strimmer is having the same problem so I will attempt this when ime free 🤞
Nice video,I like how you explain how the vent works.I am a subscriber now. Just a note I would not use the torch over the trimmer gas tank.
Thanks for the heads up... but I was not as close as it looks in the video angle
Lol....close is for horseshoes and hand gernades .
@@varminthunter I had the same thoughts concerning gasoline and a torch particularly since gasoline fumes ignite quite well too
Aww and the Karen's come out !
After messing with 2strokes one too many times I changed all my trimmers and other 2 strokes to battery. Never regretted it because with no longer wasting time with crappy equipment I'm getting more done
Been running 2 strokes for years, and I mean probably dozens, if not hundreds, over 33 yrs in the tree business. Weed eaters and trimmers , all part of the fleet. Slowly getting some battery stuff in the fleet. I keep my saws outside all the time, in the rain, etc. Never hurts them. Now, gotta consider how to keep all the electric tools, covered, and places for all the chargers and spare batteries, for all this new equipment. We are in a new age.
Everything what I needed to know.... hope it works out for me
Wow, he is a wealth of knowledge. Thank you.
Our pleasure!
Outstanding!!! This is an excellent video. Very helpful.
Glad it was helpful!
Excellent video thank you for sharing 👍🏻
Thanks for watching
Good video, because I found my problems as well. Keep up the good work.
Glad it helped
I learned that the carb. vent in the white cap assy. may be defective and not allow the "Throttle - up" condition. By unplugging it as seen in the video, it allows air to pass into the tank. I thought it was the opposite- that it vented outwards towards atmospheric air to equalize the pressure inside the tank from over pressurizing for safety. Thank You.

Very good demostration!
Thanks
Nice... my weedeater, of almost this exact model has the same issue. Scince the problem started all of a sudden, im guessing its the airhose from the tank. Will check it out. THANK YOU. :)
Really people give up to easily and don’t think things out or try something different 😊
Good job 👏
Thanks
Wow. Masterclass instructions! 👌
Great job and thanks for sharing your valuable knowledge.
My pleasure!
@@helpinguonline I'm a handy guy and have fancied myself as being able to learn to repair my own 2-cycle and 4-cycle gas tools but it hasn't gone well for me to date. The 2-cycle tools are the truly tough ones, compounded by ethanol fuel and its detrimental effects. Before one learns how to repair them, one needs to learn everything about all of the parts and what can go wrong with any of them. Only then can one be able to go about troubleshooting. I've found that a pedestrian knowledge of 2-cycle engines won't help e.g. assuming issues with clogged fuel filters and carburetors to correct restricted fuel flow, and squirting anything that moves with carburetor cleaner by itself won't help. But your video is one of the best places to start. Thanks again and Good Luck.
Thank you for helping us out to troubleshoot these little engines. If I may, I would like to ask you if you could do close-up shots of the small details. My eyes are not helping much, and again, thank you. Excellent work!
Great!! You saved me a lot of time and money.. Appreciate it dood😊❤🎉🎉
Glad I could help!
When he said “aha” I was like I’m subscribing
Great work. Thanks for taking the time to explain the process
Glad it was helpful
very good in my opinion...but the camera has to get closer, to zoom in for us novices who cant ask anything in real time. And you know wht tey say about ''ASSUME''
Nice video.
One other thing that needs to be checked is the screen in the muffler. It gets clogged with carbon and won’t allow it to run correctly.
I worked in a small engine shop and ran into it all the time. Another indication of it being clogged was the spark plug was fouled up with carbon.
Take screen out and heat red with a torch with long handled pliers. Check first when it won't run again from the last time.
Leave the screen on the bench and go back to work?
Stihl is/ was terrible for that. Losing the screen= better ruuning. Do that in Commiefornia, and, lookout.
@@treeguyablethey will never, ever, come check if the spark arrestor is in place on a piece of lawn equipment.....
Same with mine thanks for sharing your knowledge... God bless sir
God bless you also and thank you
Beautiful Catch !! 👍
I was going to subscribe to your channel watching this video, very helpful btw, when I noticed that I was already subscribed LOL Thanks for what you do my man!! Keep the good job!!💪🏾💪🏾🙏🏽🙏🏽 Sheers and blessings from Puerto Rico 🙏🏽🇵🇷❤🙏🏽
Thanks... and God Bless you!
Good fix! Cheers! 🍻 -Al
I will try this out on my 21 year old stihl trimmer, very interesting video. Jim Byrne here, watching here in Ireland 🇮🇪 😀
My Troy-bilt st75ss(I think,lol) is 20 years old ! Use it to weed whack and I have a Ryobi tiller attachment that fits the shaft for my garden. Rebuilt the carb around 2008 and haven't had a problem since. Sometimes you get lucky and get a great machine! It was my late father's trimmer and I'll never let it go, I guess because it has that tough, never quit quality like the old man. I hope he knows he picked a damn good one😉😏
Very nice diagnosis, sir. Your knowledge of small engines is impressive. Thank you for posting this video.
I am so going to be asking this man for help if I cant get this strimmer I just brought at an auction. I only had a little mess around with it earlier today and will be trying a new spark plug after I have tried a couple more things hopefully he is still active online :)
Thank you I new to this small Eng repair
Welcome!
Thanks for the lesson
My pleasure!
Great tips, thanks
Another great video. Thank you.
Thanks!
Grind the point off of a sheet rock screw and thread it in, you can yank the plastic cap right out, then do the same with the brass limiter behind that
I always empty the fuel tank when checking for water. Water is always on the bottom..If you shake the tank , then you will see water distributed in the fuel. Good video.. thank you
Exactly. Water is heavier and gravitates to the bottom, so draining off a little from the top will not be a valid test of fuel purity.
Great video really appreciate it
You are a monster fixer!
A year later still helping people
Good to hear
Thanks I learned something from that
that was pure genius
The flame over the tank thing. I can't say much, been fueling saws / weedeaters for decades, whilst smoking a cigar.😆
Another great video .... keep' up the good work.
Thanks, will do!
I like your Enthusiasm.subscribed.
Thanks for visiting and welcome aboard
Thanks for the information and video.
My pleasure!
Brother I appreciate your help
Thanks for that tip
Great done
I have same issue on effco hedge trimmer change carb and gas filter and won't throttle up i will neglect
Vent gas tank i hope same result happen with me
Theres always a problem with fuel lines expanding sucking air get the clear 3mm hose and use like bread twister to clamp them never tried the breather trick always thought the oil wasn't mixed enough in the gas. Looks like the oil separates in the gas can a little
Thanks hombre
Good class thanks 😊
Thanks, you have been very helpful!
glad I could help
Perfect! Thanks!
You're welcome!
Thanks for demo
You bet!
Great video thumbs up
Excellent information. My Echo weed eater has been driving me crazy. Starts fine but several minutes into job it starts to bog down and won’t rev up to full. Rebuild carb and checked lines. Same thing when completed. It ever crossed my mind that it could be the gas tank vent filter. Thank you.
My friend had a Stihl weedcutter from 1980’s. He removed the gas air filter and made one out of a window screen mesh leftover. He just layered the mesh with three layers, crossing over the layers. It works fine and he saved a little bit by keeping the trimmer. It works fine with the fuel mixture for the 2 cycle engine.
Try putting premium gas in it or 50 1
