Lawnmower service - Step by step / Including carburetor cleaning (HONDA)
ฝัง
- เผยแพร่เมื่อ 21 เม.ย. 2020
- Step by step how to service a standard 4-stroke petrol lawnmower, in this case a HONDA IZY. Save £££ and DIY.
STEP 1: REPLACE OIL - 1:02
STEP 2: REPLACE SPARK PLUG - 3.56
STEP 3: CARBURETOR SERVICE (If you are happy with how you mower is running and don't feel this is necessary, skip this step) The carburettor can become dirty on the outside and old petrol or sediments can also block up the inside. Cleaning the carburetor can cure hunting/ surging and starting issues. If you're confident carrying out this step, it's worth taking the extra time as a preventative maintenance measure.
STEP 4: REPLACE AIR FILTER - 12:55
STEP 5: SHARPEN THE BLADE - 13:11
AND YOU'RE DONE!
Servicing should be carried out as per the manufacturers' recommendations.
This service KIT: ebay.us/XbcL2C
Carb Cleaner: ebay.us/Naitad
SAFETY: Disconnect spark plug when working in and around the engine, especially on the blade. Wear the correct PPE, old engine oil is carcinogenic (causes cancer).

An hour of my time, a very small amount of swearing and a row with my (now ex-) wife for servicing the carburettor on the dining room table and now my mower's running like new. Thank you so much.
Pleasure 😂 sorry to hear about that but main thing is the mower is running sweet now! 👊🏻
A really useful video. My main reason for viewing was to see how to service the carbaretor. This was explained very clearly,
Thank you for your feedback, really glad you found it useful 😊
Finally, a decent, clear step-by-step with closeups!
Thank you, glad you found this useful 👍🏼🙂
Agree with other comment I feel now I can service the carburetor on my Honda after watching your video. Thanks!
Hi thanks. I used your video to remove, clean and replace my Izzy carburettor on my dead lawnmower, now it purrs. Your voice is clear, instructions concise and video easy to follow. I have never undertaken a task like this before. Thanks very much Stewart
Thank you for your comment Stewart, I’m really glad you found it useful. Good on you for doing it yourself 😊👍🏼
My Honda Izzy I started to slightly surging so I'm glad you put this video on on how to do it. Big up from Scotland 👍👍👍
Just wanted to come on here to say a huge thank you for your excellent video. Your very clear instructions allowed me to strip down and clean the carburettor on my my Al-Ko mower (the engine must be *very* similar to the Honda) and restore it to working condition, when I thought all hope was lost! Your explanation and video was extremely helpful; thank you so much!
It’s always lovely to have nice feedback so thank you for taking the time to leave your comment. I’m really glad you found the video useful 😊
Thanks for the video! Will be following your guide for servicing my own mower, I managed to tackle the oil change last year after 9 years without a service lol. Gotta love the Honda engines!
Thank you. This is quite comprehensive. I have not had the carb off yet so this section is useful. 👍 2 years since the last service so it will be interesting to see how bad the oil is.
Amazing thank you. Followed this and got my mums mower back to life-it was hard to start and kept cutting out now starts first pull and runs great
That’s brilliant, well done mate :) really glad this helped
Good job, clear and precise. You keep it nice and simple to get the service completed.
Thank you, I really appreciate your comment 🙂
Great video, I'm about to follow the steps religiously in the next couple of weeks.
Thanks mate! Good luck 👍🏼😁
Excellent instructions that are easy to follow and really make written instructions redundant.
Thanks mate 🙂
Very helpful! And no nonsense, with skip times! Well done lad!
Cheers mate 😁
Great Job Turner! Very helpful. I have a similar Honda mower I’ll be following your maintenance guide to service my mower!
Thanks man 👍🏼😁
Great video. Done oil and spark plug just about to do the carb 😂😂
Excellent video. Don't forget, ALWAYS remove the spark plug cable before starting the maintenance!
When tightening the two knife bolts, always use a torque wrench and mention the applied Nm.
Very good demonstration, learned a lot thanks for taking the time
Awesome video! Thank you for all the detail and taking your time to walk us through this.
No problem at all, thank you for watching and commenting 😊
I learned a lot. Well made video. I will never be able to clean a carb, I am afraid: you need to be surgeon! Well done!
Thank you! 😊 all the carbs I’ve come across are pretty similar and I’m sure you could!
Great video mate. Thank you for taking your time.
Excellent video. Simply and clearly presented
Thank you! 😁
Excellent step by step video.
Really useful video for my weekend Honda service.
Followed this great video today having bought the service kit from eBay with a new blade and carb cleaner. Did the full service as described and the mower runs like new. I'm no engineer so the video was really useful. Thanks again.
Thanks man, very nice video. I'm overdue on maintenance of my lawnmower
No problem! Thanks for your comment, good luck with it 😁
Excellent video. Really informative and comprehensive.
Thanks mate 😊
Got your video just in time, many thanks
Thank you very much, just about to pick up a second hand "rusty but working" one for £10.00 (Hey, for a tenner it's worth the gamble). If I don't follow your guidance soon, I'm sure I will in the future.
A great video!
👍👍👍
No problem! I often buy old mowers for around that price. Fix them and sell them on. These engines are great but unfortunately the decks tend to rot. Thanks 😊
Very informative video. Explained everything nice and simple. Thumbs up.
Thanks mate 🙂👍🏼
Awesome vid, thank you!
Really helpful, even though my mower is 16 years old it still runs reasonable well. I bought the first new spark plug recently and will put a new air filter in now. Having seen your carburettor service I might try that as well.
They are great machines 👍🏼 how is the deck holding up after 16 years?
@@TurnersWorkshop97deck their only weakness imo
Great video...very clear instructions...thanks 😊
Thank you! Glad you found it useful 😊
Very clear and informative
Thanks mate 🙂
Very good instructional video
Thank you, glad you liked it 👍🏼
I haven't got round to Honda's engine yet im still on Briggs engines but will sub for future viewing keep up the vids
very nicely done
Thank you 😊
Thanks for the info, very helpful 😁
My pleasure, cheers mate 👍🏼😁
Great video
Thank you :)
your widening that jet!
More POWER! 💥
Thanks for this. Really clear steps.
In another lawnmower video (I really know how to live 😬) I saw a comment saying they knew a guy who lost a couple of fingers when the lawnmower he was fixing jumped into life, and so now they always disconnect the spark plug just in case. Maybe not relevant on this model... but maybe?
No problem! Thanks for your comment. It’s always important to take safety into consideration and disconnect the spark plug when working on the mower.
VERY useful thank you....subscribed
My pleasure, thank you for subscribing 😊
You can use two bolts with out head to hold carburator and gaskets . Makes it more easy to install
Nice video
Thanks!
Thank you! Really appreciate your generosity 😊🙏🏻
Good Video mate ..
Thanks mate 😁
Great section on carburetor service. Blade sharpening section was poor (important to maintain cutting edge angle while grinding) but did mention that blade needs to be kept in balance. Spark plug can be cleaned and gap reset but no mention of correct gap. Air filter section very clear. Draining of warm oil was a good tip.
The Tube Down The Centre Is Called An Emulsion Tube Not A Pilot Jet. The Pilot Jet Is The One Under The Screw On The Top Of The Carburetor. Good Video
Thank you. Clear manual, at least how to make simplest maintenance - change oil and spark plug. Filter I check after each mowing.
No problem, thanks for watching and taking the time to comment 🙂
Amazing thank U 🙏
No problem 😁👍🏼
A torque wrench also to torque blade bolts to speck
Never work on a mower with the plug cap fitted. As has been said here if you inadvertently move the blade it could, and has jumped into life and relieve you of your fingers.
Nip up the spark plug?...you should have stopped after the fist tightening move as 1/8 - 14 turn is sufficient.
You warned, rightly, that the jet is brass so to take care but then you stick a steel needle into it...
thanks
Thank you so much for this video! Very informative and a pleasure to watch and learn from you. I started tonight, but I ran out of daylight, so the remainder will be completed this weekend. I appreciate the instruction! Keep up the good work! Cheers from across the "Pond"!
The pleasure is mine, thank you for your comment 😊
Superb concise video 👍 may have to strip my carb as it’s only running a few seconds then stopping. Not helped that the the last drop of fuel has evaporated in it over winter probably leaving residue in carb.
Well done 👍
Cheers mate, glad it is helpful. Sounds like it’s most likely a dirty carb 👍🏼 usually is 😊
@@TurnersWorkshop97 after leaving fuel in it over night it’s cleared. Will strip if it stalls again 👍👍
An hour of my time, couldn't get the fuel line off. Stuck fast and didn't want to tear it. I wasn't gentle either though. So couldn't get any of the springs/other cables off (except the really hair thin one). Tore the gasket trying. Gave up but sprayed the carb with the cleaner and at least it runs again (as long as the choke is on).
You gave it a go mate and that’s what counts. They can be very fiddly to work on but changing the gaskets may make it run much better.
Good video.only problem don’t poke a needle into jet hole. Easy to damage.
The item behind the main jet that you call the idle jet ( emulsion tube ) gets stuck . Some use an easy out to grab it . There is a hole which is near the top of the tube . It runs side to side . This goes towards the TOP when you put the tube in . I also clean the small holes with a wire and carb cleaner .
Thanks for your comment, great tips 👍🏼🙂
Follow up : My GCV 160 with automatic choke had debris in the carb bowl . After cleaning the entire carb , I put the emulsion tube in the opposite direction and it would not start . I reversed the tube and it runs . However , I noticed the tube does NOT have the hole that goes through the side near the top as shown in other videos . Lesson learned - be more careful in laying out the parts . There could be different tubes on some models .
Piston should be at tdc before draining oil, stops any oil going into exhaust plus I don’t change my oil every year but every 3 yrs. never had problem.
Photograph carb linkages😊great vlog thanks
How do you get the piston to TDC?
Thank you for the demo, I was just disappointed you didn't show putting the carburettor back in.
You’re welcome, thanks for your feedback next time I make a carb maintenance video I will be sure to include that 🙂👍🏼
@@TurnersWorkshop97 Thanks, your video was very good. It is one of the better ones I had seen. I like to see as much detail as possible, so I dont stuff it up 🤣. I will make sure I record myself when taking multiple wires or screws out, so I know where to put them back. 😁
Thanks for the informative video, really helpful. I have a Honda HRB 535. It propels fine but when I need to turn round it does not run smooth, jerks quite bad which does not sound good. I have changed the small cogs on each wheel as they were worn. I now suspect the wheels may need replacing as the gears may be worn, not obvious though. Any ideas ? I don’t want to buy new wheels if that is not the issue as they Re £40 each from Honda.
Thanks in advance.
Jim
Hi Jim, no problem at all. I can’t say that I’ve ever worked on a HRB 535 to be honest mate. Might be worth taking them off and checking for wear before you spend £80 on new wheels though. Sorry I can’t be more help mate
Excellent video. Really enjoying doing my first home service.
Taking the carb off, I've noticed a couple of the gaskets are pretty knackered and I have a replacement pack.
Just want to know, do they need to be fitted with an adhesive?
Thank you, the gaskets are fitted dry 👍🏼
the pilot jet that you couldnt get out can actually be poked through from behind with an L shaped allen key
Thanks Sean, will have to give that a try next time. I did try and pop it out with a screwdriver but didn’t want to move for some reason 🤷♂️
How do you take out the 10:38 "pilot jet that sits behind the main jet" out? Flat head screwdriver like the other one? Thanks!
It’s hard to explain without showing you and it was stuck in there unfortunately. But the emulsion tube sits behind the main jet and should fall out. If it doesn’t you can use a screwdriver to press it out.
I've changed the air filter, sparkplug and topped up the oil as it didnt look too bad. I removed bottom of carb in situ and sprayed carb cleaner up into it and cleaned out the sediment. The mower runs, but its like its revving ever so slightly rather than ticking over. Any ideas?
Hunting engines are usually an indication that the engine is being starved of fuel. Could be a partially blocked carb still.
Is there no other way to drain the oil? Risk of hydrolock on the muffler side? Did you close the pistons before this?
Not for the Honda Izy, this is the recommended way from the manual. Other makes tend to have sump plugs.
@@TurnersWorkshop97 Thanks, yeah i downloaded the manual in the end, was also unsure about whether or not to screw the dip stick in as the threads are about an inch so makes a massive difference, the manual said not to.
Nice video! How often does the carb generally need to be cleaned?
Thank you :) with general use once a year would be good practice to keep it running nicely. If the fuel is drained out the carb before storage in the winter time it will likely stay cleaner for longer. Old fuel sitting in the carb for long periods of time causes the main blockages. And any dirt getting past the tank filter.
@@TurnersWorkshop97 Could a fuel additive do some of the same work? 😇
Is spark plug gap no longer important?
The chances are if you are buying a service kit for your mower the plug will be suitably set for that engine. Always worth double checking though if you’re after optimum performance. Thanks for the comment
0.7mm is the correct gap
What type of disc did you use to sharpen the blade on your grinder cheers 👍🏼
Hi mate, I used a 60 grit flap disc if I remember right. Thanks for your comment 👍🏼
@@TurnersWorkshop97 thanks mate
emulsion tube
That’s the one, thanks for your comments 😁
Pretty sure my Honda lawnmower (which looks to be the same or similar to yours) says on it not to let it get wet ?! Is it safe to blast with a pressure washer, really ?
They probably say that as they’re worried about the rust forming within warranty period 😄 It’s perfectly safe just don’t spray in exhaust or inlet. Many lawnmowers have hose connection points for cleaning the deck anyway. You should always clean off the grass from a lawnmower deck after use as it’s what makes them rust badly. Whether that’s with a hose or a brush.
I don't understand why they don't fit in-line filters. Can one be fitted?
Usually there is a filter screen inside the tank to prevent dirt entering the carb. You can fit an small inline fuel filter though 👍🏼😁
@@TurnersWorkshop97 Yeah, I've seen that but it doesn't seem to stop the finer stuff. Might try a in-line and report back!
Really useful but it would of been useful if you had shown how you balanced the blade at the end
Thank you, that’s an idea for a future video. Cheers for the recommendation 👍🏼
@@TurnersWorkshop97 no worries mate
Is it fine for the mower to be tipped up like that when draining the oil? Cheers for the video!
It’s fine on the Honda Izy, it doesn’t have a sump drain plug so this is how you are to get the oil out or alternatively you could use a vac pump. No problem man! 👍🏼
@@TurnersWorkshop97 thanks for the reply! Looking at a used one of these, anything I should keep an eye out for when I view it?
Engines are usually very good, just make sure it’s got oil in it. The decks are prone to rust so that’s what I always look at. Then just general checks make sure self drive works things like that 👍🏼
@@TurnersWorkshop97 Brilliant mate cheers! Seen one that’s apparently rust free for around £130 so hopefully it’s a gooden.
No worries, If you’re planning to keep it for the long term it might be worth painting the underside with some black hammerite or similar and keep it clean. Hopefully that should keep the rust away 🙂 👍🏼
I really wish they sold the honda izys in america...
They’re fantastic machines
2:00 that's blacker than the blackest black X Infinity!!!!
(I hope someone gets the reference)
The video is good and useful, but what is the purpose of the annoying music?
Thank you, apologies for the music 😅 was one of my early videos.
I keep hearing that you should never use a power washer or wash the lawnmower like that so that water doesn’t get into the engine.
It’s never been an issue for me. It’s advised not to spray directly into the exhaust or inlet. It’s worth putting a plastic bag over the air intake and plugging up the exhaust so you don’t get water in the engine.
Turn the music down and your voice up!
What's the spark plug number please
NGK spark plug BPR6ES
@@TurnersWorkshop97 cheers mate
Often wonder how too change oil
Didn't think it would be that easy
Great video mate 👍I have now subscribed 👍
No worries 🙂 it’s easy when you know how. Cheers mate I appreciate that 👍🏼
In the GB we always screw the oil dip stick into the engine to measure the exact depth of oil.just by dipping the measure in and not screwing it down you have the depth of the thread not accounted for......otherwise not a bad vid
Thanks mate, I will double check in the Honda manual but pretty sure that for this engine it’s a dip without fully screwing in 😁👍🏼
@@TurnersWorkshop97 looks like the American way is right,just shows your never t o old to learn..even at 70👍
