I use honda whipper snippers for my landscaping business and they are amazing, got an old one that runs like a champ. Some of the Stihl ones are great as well.
Yeah the choice is simple, cleaner fumes, less vibration, less cost as 2 stroke is very expensive oil, longevity and reliability ! I'm on my second GX35 brushcutter and the first one has been with me over 10 years and still runs like a charm
@@PracticalPrimate I did - thanks again. As I got the rest done OK and the trimmer is working again I didn't try changing the fuel filter. Ill wait till it stops again!
My grandfather has had this model for like 20 years. Never been serviced. Been hard to start for the past year and now I can't start it at all. I think the motor might be locked up. I checked the oil and it's dirty but not sludged up. They're good engines I might try and get it running again with a proper tune up.
Far out, wish I would have seen this when I got my first UMC425. I don’t think I was filling it all the way, it was going to 3/4 to almost to full length of the dipstick, but I reckon it was running a bit hot for sometime filling it that way and just had it seize on me recent. I was changing it once a month as I run my own garden maintenance biz, but I reckon I wasn’t filling it properly, which was overheating it. Thanks for this, will be doing it right for my new one now.
The spark arrester is fairly easy to access too for the GX25. Just a 3mm hex allen key to remove the red plastic housing and a phillips head screwdriver to remove the 2 screws securing the arrester housing plate. Surprised how dirty mine was for only 15 hours or so use. The spark arrester is kinda spot welded to the housing plate so not sure if using the blow torch method to burn off the carbon is safe but I just used some long nosed pliers over my gas cooktop to burn off the debris, don't think I damaged the metal housing.
Being a four stroke you might have oil leak past the rings (into the cylinder) but from memory the Honda manual is unique among the four strokes in that it says you CAN hang them. Double check that for your machine. They must have tighter tolerances than some of the (cheaper) competitors.
Great vid, I have many brands of trimmers and the Honda's are my go too, as they are 4stroke they work well at low speeds around sensitive areas such as trees, pots, mesh. The 2strokes are great for other jobs that is for sure.
Great instructional video. One question: I just bought a used GX 25 and it is a winch for hauling up fishing traps... and at one point a lot of Oil came RUSHING out along the stem / behind the spinning wheel ... but I could not find the leak anywhere... What could that be? I was also wondering if it could be a Simring, but I could not locate that either. Any suggestions?
great video. would engine oil 10w40 be okay with this strimmer. yeah, i know it's not the recommended 10w30. but hey it's a 4 stroke engine oil. finally how straighten a bent shaft in one of these. thanks
Gday ive just bought s/handgx 35 ive done service, new filters new fuel hoses and primer bubble.butter after about 5 mins it bogs down to eventually stopping,there are no kinks in fuel line, what else can i do please?thank you
Very good video! do you add oil to bottom of the tread or top of the thread ? I know you stated 80 cc for GX25 .also I have 30SAE oil 4 cycle motor oil ,can I use that instead of 10 /30
Thanks mate. That was great. I change oil and filters quite regularly but wasn’t aware of filter oil. Could please do a video on adjusting carburettor on gx25 and gx35.
Hi Damian, thanks! And sure but truth be told I can’t remember ever having to do it on my machines. Usually it is just a screw but I’ll have a look and make a vid :)
Hey mate, watched and liked a few of your videos. What is your opinion on lubricating the shaft (the main section leading from the engine to the head) Also lubricating the gear housing EDIT [i think honda call it the transmission housing] (the angled section from the end of the shaft that the head screws onto) ?
Hi mate. I don’t lubricate the top end of the shaft (your clutch is in there) but yes you definitely grease the gear case (angled section on straight shaft trimmers). The service schedule is every 6 months but of course that depends on how much you use it. There is a filler bolt you undo and then you inject the grease in until full. There is a special tool for this but I just use a large cheap syringe. I might do a vid on this next time I do it :) P.s. None of this is expert opinion, I just follow the service schedule. I hope that helps! Dan
Hi, an interesting video. Thankyou. I've watched your video because I have just bought my UMK425u out of storage. All the fuel has dried up(it's been a while) and now I want to start it. I have filled the fuel tank and believe i have primed the unit.....but she wont start. Yes I have set the red switch to start AND set the choke to on. But she wont start. Care to give me a couple of tips?? It's normally super reliable (these things are the bees knees) in my opinion. Have a great day.
@@michaeldominy2084 hmm.. does your oil level drop in the sump after it leaks out or no? The only thing I can think of is you might be storing the engine upside down or sideways, oil will eventually seep between the piston rings and accumulate in the cylinder. If you then tilt the engine carb side down, the oil will go into the carb and come out the filter
@@Slenderman63323 Hi, No it’s stored in the fold position, but as it’s been stored all winter I am going to refuel , carb clean etc’ and see about getting it started to use beginning of spring.🤔😊
Hi Mick Could be a number of things sorry. I would check the easy things first, fuel filter and lines etc for blockages/ kinks or cracks. Check the breather on the fuel cap. Then the carb if you are comfortable. I have even heard of exhausts clogging up over time (they weren’t Hondas though). I’m not a small motor mechanic so best to check out a dedicated channel if it’s more complex, I recommend Steve’s small engine saloon :)
@@PracticalPrimate Sorted mate, it was the GX25! Soaked the carby in Metho for about 40mins, turns out the main fuel line was fractured, cut it back to a clean fuel line and wala! fired up and idled, more grunt too, so I'm thinking bit of tar build up in the carby and a cracked fuel line allowing more air in than there should of been. Cheers mate!
@@PracticalPrimate try rev it up warm and spray carb cleaner directly into the bowl, works a charm. In worst cases spray in and leave overnight. I revived an stale fuel Kohler that way, and a EU2000! Honda genie carb. But I'm not a mechanic so I'm sure one will tell me if this is or isn't a good idea, but as I said worked for me and didnt wreck any seals.
There seriously needs to be an absolute no nonsense statement that the oil level is at the very top of the threads. That dipstick would be confusing and it wouldn't surprise me if it was put there deliberately. But then I've always been a bit cynical.
Should have mentioned it. The schedule is to check it once a year and if you need to swap it just pull the line out of the tank, pop the filter out and put the new one in.
I''m unclear on WHY DID YOU SOAK THE AIR FILTER WITH OIL My Understanding... The purpose of an air filter is 1. To allow Air Flow 2. To filter out and dirt and dust that may be in the air intake that would otherwise go into the motor and damage it My logic here... Putting Oil in the Air Filter 1. Does not allow Air Flow 2. Would Result in Oil being sucked in What's the deal here ?
There are two types of air filters, dry and oiled. The dry filters are typically paper (think of a car air filter) and are much more restrictive in order to stop dust/contaminants. Foam oil filters (like on most machinery and a lot of the aftermarket car/motorbike filters) are less restrictive and require a sticky residue to catch dust and prevent it from entering the engine. Filter oil is very sticky and after it evaporates it leaves that sticky residue behind. Without being oiled these filters don’t work properly. I hope that makes sense.
@@PracticalPrimate First thanks for the quick response does it make sense ? Part of it YES, the part about the 2 types of filters the part that doesn't is.... in the case of the spongey filter , if you spray oil on it and it evaporates and it leaves a sticky residue by it's literal definition of how you desribed it, it would impede air flow, I understand the STICKYNESS would catch dust, but it would also get lodged into the cavities of the sponge and create a higher density environment for the air to pass though Unless this was an oil filter.. THAT i would understand, as it filters impurities from the oil, but, it's an air filter I don't get the logic of putting oil through an air filter it'd cause more stress on the engine wouldn't it ?
This is extremely helpful, thank you!
Nice work mate....had my GX 25 since 2008 and its never missed a beat...
that's incredible, I guess Honda reliability is a real thing!
Thanks mate, very clear video, well articulated instructions.
A big help with practical instructions and no bs.
I use honda whipper snippers for my landscaping business and they are amazing, got an old one that runs like a champ. Some of the Stihl ones are great as well.
Yeah the choice is simple, cleaner fumes, less vibration, less cost as 2 stroke is very expensive oil, longevity and reliability ! I'm on my second GX35 brushcutter and the first one has been with me over 10 years and still runs like a charm
Plus more torque and less bogging down than a 2 stroke. Not sure why all honda air filters break down like that?
Just bought that exact tiller here in the states for half off since it was missing the air filter and the plastic cover. Thanks for the tips on care.
I also have a gx 25 weed trimmer and i love it. That 4 stroke sound is sooo nice😂
Simple, clear and to the point. Great video, thanks for posting.
Great - very helpful! I am actually looking to see how you change the fuel filter.. .but this helped me anyway. Thanks.
Great Steve :) did you get it done? Should just be pushed into the end of the fuel line in the tank.
@@PracticalPrimate I did - thanks again. As I got the rest done OK and the trimmer is working again I didn't try changing the fuel filter. Ill wait till it stops again!
This video was absolutely perfect for what I needed 👍🏻
Thanks a million!!!!
Glad it was helpful!

How did it go?

Thanks mate 👍 Hope things are well with you. Have a great Christmas :)
God bless you for clear explanation
Very informative video.Excellent.
Can you see any reason why I shouldn't hang my Lawn Edger (GX25 motor) rather than keep it stored on the floor.
Being a four stroke you might have oil leak past the rings (into the cylinder) but from memory the Honda manual is unique among the four strokes in that it says you CAN hang them. Double check that for your machine. They must have tighter tolerances than some of the (cheaper) competitors.

Absolutely :) Hard to beat a big 2 stroke for all out power, but much nicer to work with the 4 strokes around the garden.
Nice one mate !!
Cheers mate! very informative
Glad it helped!

How many days should the oil be changed?
Hello, what about the fuel. Does it mix with oil?
@@JorgeQuezada-v3d hi. These are 4 stroke motors so no mixing required.
Great info. most helpful. Unfortunately no one has air filters in thailand; sell only. no parts for service. Assume i can clean; wash air filters
Hi want to ask you.
Your GX 35... Carburator once start engine
Whether it begine is leaking?
How do you lubricate the shaft on the honda 4

Hi there do use the filter foam oil on the lawn mower filter?
very helpful
My GX35 is not starting...it was taking alot of pulls to start, and would cut output eventually run. But now it's not starting at all...any ideas?
Very good video! do you add oil to bottom of the tread or top of the thread ? I know you stated 80 cc for GX25 .also I have 30SAE oil 4 cycle motor oil ,can I use that instead of 10 /30
do you have to mix the gas with oil like you do for a chainsaw ?
No being 4 stroke you just use gas :)

On the Gx25 do I add 2cycle as well in the gas?
No it’s a four stroke so just the petrol/gas.

What's the use in having the dip stick....it seems to me that you put too much oil in...
I would argue there is no use to that dip stick.
I’ve looked everywhere for that oil tray/container you use but can’t find it. What’s it called or where did you buy it? Cheers, great vid.
All good, found it, SCA. Thanks
Glad you found it Nick.

2 years but i'm not sure

are these good machines
Hi, Do you have any idea why on my GX 25 leaks the oil out of the filter/ carb’ area after I have filled with oil.🤔
Probably the oil on the filter is just dripping out. The engine oil is in a completely separate sump. You have to periodically re-oil the filter
@@Slenderman63323 but where would the oil be coming from to get in the filter.?
@@michaeldominy2084 hmm.. does your oil level drop in the sump after it leaks out or no?
