- * VISUALLY EXPLAINED
Here's some good reasons why your chainsaw won't start, or run, because it is flooding with Petrol Gasoline Fuel. A vital tool in your toolbox is knowledge. Without knowledge, no one can fix anything.
Any of these problems on a 2-Stroke could mean Engine Flooding. I talk to you and explain deeper understating why, which will remove a lot of headache! Here are 7 causes of Flooding to Prevent.
This principle works for most types of Chainsaw saws, and the following also helps with Chainsaw maintenance. So, whether you are using a Stihl Chainsaw, Husquvarna Chainsaw, basically, all types of Petrol Chainsaw are valid for this principle, as well as many types of or a 2 Stroke Engine. The Electric Chainsaw, of course, escapes this whole principle!
If, by the way, you are having problems with your Chainsaw Not Starting, then please do take look at my other video, where I help you get back you and running again if your Chainsaw Won't Start, or your Chainsaw Won't Stay Running. • Chainsaw WILL NOT STAR...
Many Thanks Indeed

Hi guys I just wanted to Introduce to you my other Channel "Things to Know" - which i'm just getting started. It's a go-to channel for insightful worldly explanations, handy tips, and expert advice on everyday things and repairs of domestic items. Here is the link: ua-cam.com/channels/O8P9x5kUZ44Fb11vanLFsg.html
You give the best explanations and pictorials that I found on the internet.
Dear Sir, I just want to say thank you for your support and advice. I have been working with a Stihl 020T that has been showing all the symptoms you’ve covered so well I’m this instructional video. After replacing the air filter, the spark plug, and lowering the needle valve lever, the problem has been resolved. What a satisfying accomplishment to get this old saw back into a condition that is ready to go into service at work. I am an arborist in Pennsylvania and you’ve really helped me. Sincerely, Kyle H.
Dear Kyle H.,
Thank you so much for your heartfelt message! I'm truly delighted to hear that the instructional video and the advice provided were instrumental in getting your Stihl 020T back into prime working condition. It's fantastic that you were able to diagnose and address the issues so effectively, and I can imagine the satisfaction that comes with reviving an old saw for your arborist work in Pennsylvania.
Your kind words and the fact that I could assist you mean the world to me. If you ever need more help or have questions in the future, please don't hesitate to reach out. Wishing you continued success in your arborist endeavors, Kyle! Keep up the excellent work! Craig
#8 : Clogged spark screen, inhibits spent fuel from exhausting, and fresh fuel coming in doesn't have anywhere to go, , , ,now the plug won't ignite the fuel etc. I'm a big fan, thanks for all of your videos
I'm watching and learning so much useful information from your videos, thank you!
Great job very accurate and detailed explanation.
extremely helpful!
Very well explained, thanks
Thank you.
Good information.
My Echo SRM225 trimmer turns on and then runs for a couple of seconds with the trigger pressed and then turns off instantly. After that I try to turn it on and when I pull the starting cord it begins to spit fuel mix out the exhaust and won't turn on again until I dump out the flooded fuel mix and let it sit for a bit , but still the same events take place later. My research brought me here to understand what the diaphragm does and I ended up learning more of what to expect before I go spend money on something I may not need or I may need more parts all together. Either way I'm eager to do it myself , THANK YOU for increasing my manliness to the next level by giving me your knowledge....lol
New subscriber fantastic video I'm always trying to learn more about carbs. This video is incredible my man 💪
Very good explanation of flooding problems with two cycle engines I watch this because I'm having a flooding issue with my chainsaw and now I feel I have more information to go after the problem two-cycle engines can be a real pain in the butt when they don't work right they will drive you completely insane trying to fix them.
Great explanation .well done 👍
Thank you very much for the explanations.
You are welcome! Thank you so much. Craig 👍👍
Nice job bud! Thanks
Your videos are outstanding, sir! New subscriber here. I never truly understood how a two stroke carburetor works until I saw your videos. Your illustrations are straight forward and very easy to understand. I haven't seen anything like it on UA-cam. WELL DONE AND THANK YOU!
I picked up a used Poulan 4018(Wild Thing) cheap just as a backup saw. It ran when purchased, but I noticed it stalled easy.
That didn't last long and it would run intermittently good or Stalling constantly. I pulled the Carburetor and did a Full strip down and cleaning. Flushed all passages, checked needle height and inspected the Diaphragm. Reassembled installed and tuned the saw. It ran well and cut without issue.
A few uses later it started shutting down when warmed up(Coil failing) and eventually quit firing. Replaced the Coil... and of course had to tune the Carburetor again.
*I started and warmed up the saw every day for a week without issue. Seemed like problem solved.
Took it out and cut up a couple dozen 3" to 6" limbs. noticed it was slightly Fat raising the throttle(slight stumble), but got the job done.
Next day I intended to finish the limb work but the Saw was having a hard time throttling up and stalled several times. I could start it on High Idle but had to shut it off after finishing cuts and use High idle to start it again.
I attempted to make Jet adjustments but the saw would not stay running long enough to get the tool on the screw. Even raising the Idle screw wouldn't keep it running.
Notes:
Cold - Saw fires on choke and Starts on High idle(choke off) but runs very rough.
Bumping off High idle - Saw stalls as soon as Throttle is released
Spark Plug(new) - Fuel Soaked
Closed L to 1 turn
Closed H to 1.25 turns
Wiped Plug Dry, installed and Started saw on High Idle
Same result when bumping to low idle - Saw stalls and Plug is flooded.(Dry/Start/Stall/Flooded - Repeatable)
**I am 70 and eye sight is failing. Needle looked good, but I cannot focus on the Jet seat itself.
My thought is on assembly the Needle was installed in a slightly different rotation and was close to, if not completely, sealing. Through use it has rotated and is now allowing Fuel to pass from not seating.
Your Video is an excellent refresher and after reviewing the Valve/Seat section I am convinced this is the issue and will be ordering a Replacement Carburetor.
Thank You!
We appreciate you sharing your thorough Poulan 4018 (Wild Thing) experience. You've obviously put a lot of work into maintaining and diagnosing it. It's wonderful to hear that the video and material were useful to you in troubleshooting.
When it comes to carburetors, especially if you have acquired this from previously used, then stripping the carb and servicing it is always best done by using a new service kit with new diaphragms etc. I know you probably looked at the diaphragms and thought they looked ok. But believe me you can't always tell the functional condition of these by touch and feel. Also, in the kit, there is a new needle valve, which will likely seat better than the old one. You will also get a new (tensioned) metering spring, which will seat the new needle better. When you had the old need valve out of the carb, could you see a ring around it's tip. I know you said about your eyesight, but if you get chance to take it out again and see (using and magnifying glass) then the presence of a ring will tell you if it is wasted. A diaphragm service kit can be bought for as little as $15 nowadays.
Other than that, I know here you are coming from here. I have spent hours upon hours trying to get some carburetors up and running, and on occasions I have had to just say "you know what, it's time to fit a new carb". I wouldn't usually be so quick to say this but given the details in your comment, you sound like a very knowledgeable person in this area, which means you have probably done all that most people would be able to do. I know it is nice to tinker a little with these things but for me, when it gets to this stage, the time isn't worth the money I would be failing to earn due to trying to fix it. I find that forthe the price of $25 a brand new (non genuine) carb, from Amazon, usually does the trick reasonably well. Well, much better than before anyway. This way you will be up and running much quicker and better.
I'm not just trying to just take the easy route here, it's just that i totally understand your frustrations. Carburetors, like other things, sometimes need to be replaced. I have wasted too many days to no avail with some carbs and I have found this to be be the best way of dealing with it.
If you do choose to get a replacement then please let us know how it works out, and don't hesitate to contact us again if you need help in the future or have any other questions. It is quite admirable how committed you are to maintaining the condition of your equipment!
I look forward to hearing from you, and thank you for contributing to the community

@@TheRepairSpecialist Your quick and through replies are always welcome and appreciated.
The Needle is the Solid hard type and no wear ring was noted. This is what leads me to believe the softer seat is the culprit. If I were Younger I'd take a drill bit to the seat and smooth it to renew the surface, but now my hands are a bit to shaky for the fine work.
I do agree, kits are an easy route to refreshing a carburetor, but for the $2-$3 difference in price and all the extras I can get with the Carburetor(Air Filter, Fuel Lines, Purge Bulb, spare Spark plug, etc.) just makes replacement the route to go.
I have always had this thing about having a good look before throwing money at a problem, often resolving the issue in the process for less or no investment. Then if necessary, replace.
As for the Diaphragm and Spring, I was satisfied Both were in decent working order from the Week of test running and full day of Cutting with excellent throttle response and decent Idle.
*After I swap out the Carburetor I'll pull a vacuum test on the Fuel feed side, I suspect it will fail.(I have to replace my vacuum tester - Brake Fluid infiltrated and ruined its seals)*never loan tools - lol*
On a bright note, Yesterday I finished running Break-in cycles and slight tuning on my 2nd 4-stroke 49cc Chainsaw. Picked the first cheap($89) a year ago and have worked it hard, LOL - Really Hard. It went through over 10 cords of hardwoods with nothing more than regular Cleaning and a few chains(now I sharpen) before worm gear Failure caused excessive Sprocket movement, throwing chains. Contacted the Manufacture to get parts for Repair(all wear items)......... and they ended up sending me a Free Replacement, complete.
I've sourced all the parts through AliExpress to restore the original.

Thanks again for the knowledge you share!

Be sure to check the gas cap vent first
Thank you for your video's, they are one of the best explanations of 2-stroke engine, you got a subscriber. It is more a user error, I thought that the primerbulb should push petrol in to the carburator and I thought as a beginner that it is normal that there is petrol comming out of the carburator, but it was the otherway around I found out, sucking it through the carburator. So you can put to the list a wrong connected primer bulb causes also engine flooding...
Wow, I didn't know that the shape of the diaphragm can be corresponding but the shape of the height doesn't fit well and push the needle more or less than ideal... And the needle seats wearing? Wow true revelation 😁😅!!! And the fuel quality!?! Just unbelivable... Many thanks for this professional teaching and keep up the good work... 👍

Thank you so much sir 🙏
Great video, I have had problems with bad coils causing insufficient spark as well, cheers
Thank you for your awesome comment. I really do appreciate it. Craig 👍
You have helped me greatly.
Thank you for your hard work
Thank YOU so much for your views and kind feedback. I really appreciate it. Craig 👍
great video, you explained it really well
Thank you! I really appreciate it. Craig 👍
Clear and useful explanation.
Thank you so much
Im working on my ms310 that sat neglected for a few years. Ive rebuilt the carburetor replaced all the hoses,and tuned it up,but but its flooding soon as it starts. With the air filter off it spits fuel back out through the carburetor as it runs. I can only get it to run for about 30 seconds. Ive double checked my float lever height twice and can only conclude the fuel is leaking around the seat. The needle was frozen in place when i rebuilt it and i had to slray it with pb blaster and use needle nose pliers to remove the old needle. Id say its corroded or has some other deformation
Should say that the lever is set flush with the carb body, ON THIS PARTICULAR MODEL, while other models have their own specific set point in relation to something on that model.
You are the best.😊
Thank you so much 😀
Informative video,thanks....
My specific problem is that I put a new air filter in my 075 Stihl and run it,
It will fill the filter with fuel mix and choke it self..
Replace the filter ,same thing....got any thoughts?? Thanks Walt
Hi. I have fuel coming out of the carb soaking the airfilter and pooling in the air filter housing, when the 2 stroke Echo hedge trimmer is running or not, what could cause this?
Sir please teach about missfiring problem in 2stroke engine
Wow such great videos! So what symptoms would indicate that flooding has occurred? Obviously you listed the causes but how do I know an engine is flooded? Would you just pull the spark plug? What is normal under the spark plug? Some fuel? No fuel? Thanks!!
Need your help mate, whats the piece between the carby and the piston head on a 2stroke brush cutter?
Another issue relating to needle valves could be dirt particles being stuck in needle valve seat area, preventing needle valve to make a complete seal. Strange that you missed this one friend.
I appreciate your videos, the way you explain band I have learned a lot but there is a point in this video I don't agree with you. You say the lever level must be leveled with the diaphram base seat but in my opinion is not exectely like that by the reason walbro and zama have lever gauge tools to set the needle lever and its level varies to the carb type. Please correct me if I' wrong
Yes you are right for some of them. I should have mentioned that some carbs are set the way I explained and many others are not. Good point! I will look at amending that. Thanks. Craig
Explain band ? Explain and. Correct grammar. Correct if I wrong, correct me if I am wrong correct grammar.
@@TheRepairSpecialist think I need new air filter 😑
I just have a spot of fuel on my air filter. Now I'm too smart-by-half.
A woman trying to fix her generator. Finger nails black and feeling so clever. Ha ha. Your video is fabulous. Thank you. My gene is fixed!
