Never ever attempted to fix a mower in my life, mine is a similar one and has the same sv150 engine with the lhp16 carb. It would start then just stop in a few seconds, last night, after watching this video about 3 times I ordered some carb cleaner and got my tools ready for the next day. I stripped down the carb after clamping the fuel, soaked all the bits in the carb cleaner and reattached that little spring that had also gone on my mower. I then gave the carb exterior a good sloosh with cleaner and a soft brush. I put it all back together after checking for leaks attached the airbox. Started first time and runs better than it has ever done!!! Thank you so much one dead mower fixed for a 6 quid tin of carb cleaner!! Liked and Subscribed!!
Thanks very much for your expert video, the little spring was my problem, without your video the mower would have been taken to the dump. With the assistance of your video, she lives to mow another garden :-)
Great video - thank you. Explained “why” a little too which is helpful for casual users like me. I had wondered why my mower didn’t tick over when I wasn’t holding the handle. Answer is that it doesn’t 🤦♂️😅
Thanks Mower Man, great to get all the detail and tips. I had very slow running on my XSZ40 so turned in the running speed screw to resolve (it has an anti-tamper pin in the crew head but turns by hand anyhow). Might clean down the carb if issues persist. A few notes that might be useful. a) mine doesn't have a micro-switch for the engine cut-off - just a sprung metal contact that a cam operated by the cable touches with a single lead (shorting cable) to it (cost saving!). b) the little extra bolt at an angle on the float bowl is a drain plug if you want to drain the fuel off. c) the upright bracket on mine has a clip at the top for holding the fuel pipe mid-way; clearly missing on your example. d) the very light spring on the throttle (also bit of sponge under it) does not control the full travel of the butterfly valve as you said. I suspect that is not supposed to operate the full range of travel - this is done by the main spring on the regulator arm - just provide some damping as it gets toward the end of travel? Also your website appears to be down at the moment - I have tried a couple of the links and none working.
My lawnmower is alive again thanks to this video.. a new spring for the carb and the tension sorted and a new plug along with a good carb clean and waaaahey fires up with a simple pull.. My mower has become super loud though I’m guessing the muffler is knackered .. if you ever get the opportunity to film one of these and changing a muffler that would be ace.. great work thank you
Many Thanks Mr Mower Man! With your video I fixed our sovereign mower today! From what I could see there were 3 issues, one - there was a hole in the fuel line near the fuel inlet to the carburettor (luckily there was enough fuel line to snip it off & reattach & clamp what was left), two - the spring on the “bracket” assembly that controls the butterfly valve, three - the spring on the linkage was loose & didn’t seem to be properly attached at the far end. Sorted those & now it runs better than it’s ever done! Thanks!
Great video thank you so much, picked up a non runner sat outside neighbour house for year, will use as back up mower, engine recoil had snapped, new one from Ebay £20, oil change and followed another vid of yours about the self propel and clutch cable as drive went from not working to new belt meaning permanently in drive, freed up the mechanism and drives, so £30 all in now have fully operational back up mower. Thanks so much love a good tinker but would not ha e done so without watching you vid and gaining some confidence, keep up the great work!! Lee
Thanks for posting this. I've just watched it this morning and overhauled the carburettor on my sovereign mower as it had been running rough. Sure enough that stupid spring had come off. Anyone can see it is not suitable for the job. Thanks again for your help.
Thanks for such a clear & informative video! My Sovereign had (what I later learned was!) a detached governor spring. I contacted the agents to find out if they had any info. as to where the spring located and they gave me a link to this video of yours. After watching the relevant section, was able to re-attach it correctly. Brilliant!
I have spend hours online trying to buy a new carb for the SV150. It seems that all of them are the (new?) model with two butterfly valves and will only work with paddle-style governor (mine is internal as in this video). Also all of the new ones have no connection for a primer bulb. I am at the end of my wits and about to throw this whole Sovereign nightmare into a skip. Does anyone have any info where to get one? Thanks!
Thanks for the video, I pulled a similar sovereign mower out of a skip today and I ran so badly, probably why it was being thrown out. I set the carb the same as you did in the video and it now works perfectly, looks like the previous owner had the carb of to get it running properly but set the mixture screw to 6 turns out and the float bowl wasn't on properly. Now I have a free mower and don't have to use an extension lead all the time to cut the lawn
I'm working on my neighbors mower. The push along version. It got bad running and fuel leak so looking to see what going on with the Carb. Thanks for doing the tutorial, a real must see.
Perfect video. Gave me the courage to clean out the rust from my carb I need to do the job again with carb cleaner but got the grass cut for today and perhaps the rest of the year.
Just about to do one of these picked up for £10 on face book got spark,fires up on carb spray down spark plug hole , reason it did not fire up is the spring detached and a small stick wedged up in governor arm against engine casing .so will be stripping carb down for a clean service as per your tips on video very informative and helpful advice.cheers steve
I've just got this model of lawnmower for free! However, the back wheel is seized, how would I go about freeing up the wheels and the belt is missing. Not even tried starting it yet. Thanks
Great video. Thanks for posting. Just one thing. The Amazon link for the air filter doesn’t look like the one in the video. The one on the link is a yellow one with a hole in it? Thanks
Great video. I have one of these lawnmowers and it requires a really good cleaning & service around all the linkages, govener etc. Well worth the watch and your experience demonstrating how it should be done.
Just discovered your channel as I picked up the exact same mower today. Want to clean the carb and couldn't wished for a better video. Very very well made, covered all the basis and the linkage settings are invaluable to a mutt like me! Cheers!
I've got the exact same mower, which coughing and spluttering a bit Thanks so much for this video. Really clear, precise and well presented. Stay safe.
Brilliantly useful video, saved me a whole lot of hassle. Mower wouldn't start, so followed your vid, stripped and cleaned the carb, and now it works a treat!! Great little tip about wrapping the spring around once more too ... thank you. 10/10 :~))
Great video ive just picked one up for nothing but have a leak on back of the carb 21.55 in video bottom right of carb how your holding it and suggestions how to fix please ?
Fantastic videos. Over the whole lockdown period this year I’ve been keeping busy by learning the does and don’ts of repairing lawnmowers. Since it’s now easier to get hold of mowers I’ve had quite a few. Need a larger shed now. 👌👌👌👌👌 keep up the good work and look forward to more videos.
Great videos, last year i followed with your help and ordered and fitted a new bulb. Lawn mower out for first cut. Petrol is leaking out through prim bulb. Help please.
Great vid Paul! I remember, here in Canada walking endless miles through the vast boreal to school in the 1960's. And it was always windy. Way windier than things are now.
I have the exact same mower I've been using it in my allotment for 2 years, but yesterday i tried and tried it didn't start up? What's the the first thing I need to check?
Love the video, found the problem with mine it was as you suggested a slack spring. However mine was slack as it’s broke, any ideas on where I can get a replacement carburettor?
Another good un Paul , I use to sharpen blades the same way I now use a cordless angle grinder wit a flappy disc , not a big deal just find it quicker and easier, can even do it whilst blade is on the mower
Thanks for the video, very helpful. Working on the same mower for a friend which he brought to me as it was clearly over revving. The throttle doesn’t die back after starting and the mechanism is completely free moving and springs are in the right place. I can relocate one of the springs to the wrong place to artificially hold the throttle against the idle screw and it runs fine but obviously this is not what is intended. Any reason why it is not self governing or does this mower run at a ridiculous RPM?
Hey , loved this vid i have a self propelled version but at the local dump the yesterday i found one of these and asked for it for parts. I'm now thinking i,ll try to save it. Please link me to a gasket,wee carb spring and other parts suppliers. Thanks again.
Hi great info. There looks to be two different types of carburettor's for the SV150. Do you know where you can buy the SV150 carburettor with primer? The choke switch you find on all "for sale" SV150 carbs on the net. Mine has a chip out of the shaft that the fuel bowl screws into and a fuel leak (float full of fuel/missing pin seat).
hi had had a suck pull cord what i fix however when i took pull start off i found a broken part witch im not sure what it is or where it go mower starts and runs but when it stop it dont sound right could you help me to have a clue what it is an where it go i have the part is there a way i could send you a picture off the part thanks
The spring he talked about that you need to wrap around a few times, I've ended up taking mine off and not know how to put it back on again 😕, also I've lost the material washer thing that goes on beneath it that keeps the spring in place. Anyone know where I can buy replacements, and what these things are actually called!?
Hi. I’ve got an Al-Ko Easy 4.2 P-S and I’ve service the carburettor thanks to one of your videos. I’m waiting for an air aerosol to give the jets a good clean. My question is what spark plug does this mower use. I’d like to put a NGK in it but can’t find any information on what one it should be. Thanks
Excellent video Paul. I like the fact you took time to explain many of the carb processes. All in all looks like you got yourself a good mower to sell. Hope you make some bucks off it. Thanks for sharing.
This is amazing as I have this mower, same as you only paid £20 as pull cord was broke, just had to rewind the cord and works a treat, mine runs lumpy though
Hi, What a great video. My mower has hunted badly & been difficult to start for a couple of years. Having watched your video the return spring is missing completely. Do you sell spares please? thanks
Hi pal fancy showing a small video of how the pull cord system is on this model. I've had trouble getting the coil to recoil when the cords pulled. I think the coil that was in it was put in wrong.
Yooo mate. How’s it. Good little fix mate. Oh come on you love an sx150. I’m working on an sv200. And it’s being a git. A good video with lots of information
Thats a nice looking mower you did well there, They do start better with the primer , one thing i dont like about the carbs is the gaskets are expensive
When I opened my carb identical mower to this, it had a kind of gel around the needle and in the chamber. I cleaned all off with carb cleaner and cleaned all jets. rebuilt carb and tried starting again but no start Stripped down again 2 days later and the carb had rust in the bowl and crystallised wax around the needle area again. Any idea why this would happen please? It's the exact same one as you are working on in the video
Pull the fuel line off near the tank and see if there is a little filter in the fuel line thats gunked up. Let me know. I only found this after filming the vid. Let me know please
Spring disintegrated when tightened up crap design. I do have another LHP carb for sv150 but that has another black plastic spring arm opposite the steel arm but doesn't have a primer connection would that work on this mower?
Hi mate, great detailed videos. I was just wondering where you say about the choke closing on start up mine has only got a dead mans lever and no throttle adjustment. Serviced the carb and governor springs all present and correct but still won’t start also changed the plug.Any ideas at all please 🙏🏻.Many thanks
@@MowerMan Thanks for that, i checked that before but I haven’t a filter on and have blown through the pipe to make sure free flowing but that never helped, can’t see how the coke will close without and throttle adjust to start it
Hi that's runs great but as you said it's not popping or anything but I've just serviced a 35 classic and when its running its popping I've checked everything coll cap, flywheel key, cleaned carb with gasket and diaphragm and new plug any idea on wat it could be
ady Miller Check the O ring seals on the back of the carb where it pushes back on. Sometimes the plastic carb is warped against the metal tank so you don't get a good seal. If it runs ok without stalling or revving up and down i'd leave it.
Please could I have some help , I have tried fixing my mower , I haven’t no luck , I put some fuel direct into the spark plug hole and it started to plotter for like a 2 seconds and then cut out. Any help pleas
Also if I need a replacement carb do you sell them on your site if you could point me in the right direction would be great it’s deffo a mountfield sv150 sovereign mower I have
I am trying to get one of these working for my neighbour, I have replaced the filter, petrol cap and the blub as they were split, but the bulb doesn't seem to be drawing up any fuel
I have serviced the carburettor, but I don't think fuel is coming through, I can hear the air when pressing the bulb, it's got a full tank and knows it's coming through the fuel pipe as I had to clip it
I have serviced the carburettor, replaced the filter, bulb and the spark plug. It now start but dies within 10 seconds, do you have any ideas? I don't hear the fuel coming through when I press the bulb...Would not have been able to do any of this without this amazing video :-)
Thanks for this video, mines losing fuel and I will strip my carb. Any chance you can point me in the direction of the Gasket for this exact mower, I can't find one anywhere.
If you're losing fuel and there isn't any apparent damage to the fuel tank or fuel hose lines, then there is a possibility that the needle valve inside the carb isn't seating properly due to dirt. Your carb will need a strip down and a thorough clean. I had the same mower that's in the video. I bought a fuel shut off valve and fitted it between the fuel tank and carb. Simply cut the main fuel line and fit this shut of valve. Saves mucking about. As for the gasket you can get them on ebay as a kit. Just go on Ebay and type Sv150 carb gasket. You'll see a o ring and a gasket. You can also get the shut off valve on there as well.
Hi, great video really helpful mine is also missing that little spring thing on the top that you wound back around to resolve the hunting issue, could you send me the link for purchasing, could not see it on your webpage Thanks again
Yes. I had the same problem. The needle valve in the carb wasn't seating for whatever reason so I fitted a shut off valve. Never failed so far and that was 3 years ago now.
The point is as long as it works in the end , mixed views will always come ( fk people & there view point , you do a decent amount of work so deserve the reward 👍

John Herridge ngk b2lm will work.
Good we watch ive just bought a sovereign xss40 and cant find the blade boss anywhere do any other machines use the same part
If you are in the UK give garden hire spares a call quote the numbers on the silver sticker on the mower
Excellent video Paul. I like the fact you took time to explain many of the carb processes. All in all looks like you got yourself a good mower to sell. Hope you make some bucks off it. Thanks for sharing.
D Butler I do my best! Glad you enjoyed it!
I’m going to have to buy a Jew carb for my Xsz40. However I can’t find one anywhere , have you a link please for one
Great video mate very helpful and done a great job at fixing it properly back together and showing people how to do it keep up the good work mate
hardcore fisherman Cheers Hardcore Fisherman I appreciate that!
This is amazing as I have this mower, same as you only paid £20 as pull cord was broke, just had to rewind the cord and works a treat, mine runs lumpy though
01arron Servicing the carb should help with that!
Thank you I will have a look when I’m able to get it out
How do you adjust the valves on these please
Can you use car engine oil? There must be an acceptable type which is close to SAE30, any ideas?
Hi, What a great video. My mower has hunted badly & been difficult to start for a couple of years. Having watched your video the return spring is missing completely. Do you sell spares please?

Thanks. Try garden hire spares
Hi pal fancy showing a small video of how the pull cord system is on this model. I've had trouble getting the coil to recoil when the cords pulled. I think the coil that was in it was put in wrong.
I have vids of my channel on that. They are all very similar
Yooo mate. How’s it. Good little fix mate. Oh come on you love an sx150. I’m working on an sv200. And it’s being a git. A good video with lots of information
Haha cheers Mick! Hope it gives you hell lol! There's your dinner!
Mower Man oh ta mate lol
Good day mate love your videos thanks for the information
aldric Racette Thanks for watching! Much appreciated
My exact mower started over revving. What do I do
good man. where can i get that same carb that's on this machine?
Thats a nice looking mower you did well there, They do start better with the primer , one thing i dont like about the carbs is the gaskets are expensive
Roy's The Boy Cheers Roy! Yeah that's why I fixed it! Rip off!! Enjoying the vids Roy.
Cracking job Sir 👍 Tam.
B. Thanks!
Mower man
I have a problem . My recoil starter spring is broken . Module is xss40a would they use the same recoil unite as this mower ?
Yes they are the same. Any sv150 pull start is the same.
Any idea how you replace the red primer bulb ?
Dreadful mowers those but you've done a good job with it & I especially like your tip on the spring...that should help some owners out a lot
Andy K Cheers Andy yes I hope so!
Thanks for the link lawn Mower man. Would you have a link to the gasket I would need to replace between the carb and engine please 😊

Andy
Hello mower man do you know where i can get them springs from which u was on about at 20.30 cant seem to find them thanks
AJP Garden Machines Good question but no I cant find them either
@@MowerMan ok no problem mate i will keep searching
When I opened my carb identical mower to this, it had a kind of gel around the needle and in the chamber.
I cleaned all off with carb cleaner and cleaned all jets.
rebuilt carb and tried starting again but no start
Stripped down again 2 days later and the carb had rust in the bowl and crystallised wax around the needle area again.
Any idea why this would happen please?
It's the exact same one as you are working on in the video
Pull the fuel line off near the tank and see if there is a little filter in the fuel line thats gunked up. Let me know. I only found this after filming the vid. Let me know please
@@MowerMan will do
Spring disintegrated when tightened up crap design.
I do have another LHP carb for sv150 but that has another black plastic spring arm opposite the steel arm but doesn't have a primer connection would that work on this mower?
Hi mate, great detailed videos.
I was just wondering where you say about the choke closing on start up mine has only got a dead mans lever and no throttle adjustment.
Serviced the carb and governor springs all present and correct but still won’t start also changed the plug.Any ideas at all please 🙏🏻.Many thanks
pull the fuel line off where it goes in the petrol tank. Sometimes there's a filter in the fuel line that gets clogged.
@@MowerMan Thanks for that, i checked that before but I haven’t a filter on and have blown through the pipe to make sure free flowing but that never helped, can’t see how the coke will close without and throttle adjust to start it
@@skywalker070369 It will be automatic. Have you definitely got spark? does the plug look wet when you have pulled it over a few times?
@@MowerMan hi mate, yes I have speak but have ordered another plug to try it, the plug is also wet
@@skywalker070369 did the mower work before you tried to service it?
Hi that's runs great but as you said it's not popping or anything but I've just serviced a 35 classic and when its running its popping I've checked everything coll cap, flywheel key, cleaned carb with gasket and diaphragm and new plug any idea on wat it could be
ady Miller Check the O ring seals on the back of the carb where it pushes back on. Sometimes the plastic carb is warped against the metal tank so you don't get a good seal. If it runs ok without stalling or revving up and down i'd leave it.
Hey bud where can I get a carb for one of theses please
Hi how can I contact u please in regards to my mower the same as this but with a slightly different carb
I want a carburettor for this mower. But I can’t find one identical to the one that’s on. Can you tell me where I can get one please.

Please could I have some help , I have tried fixing my mower , I haven’t no luck , I put some fuel direct into the spark plug hole and it started to plotter for like a 2 seconds and then cut out. Any help pleas
You need to service the carburettor
@@MowerMan thank you for such a quick response

garden hire spares
Video came just at the right Time Paul, Watching / Bidding on the same Mower on ebay .........
Pigeon World Forum Good luck'
Reassembled the Carb. I bent the tang down quite a bit. So far no leaks!
Hi at 21:48 what are you hooking the spring on to get tension?mine is just un coiled with one end straight and other hook shaped
Also if I need a replacement carb do you sell them on your site if you could point me in the right direction would be great it’s deffo a mountfield sv150 sovereign mower I have
I just wind it round and attach it anywhere that works
I am trying to get one of these working for my neighbour, I have replaced the filter, petrol cap and the blub as they were split, but the bulb doesn't seem to be drawing up any fuel
I have serviced the carburettor, but I don't think fuel is coming through, I can hear the air when pressing the bulb, it's got a full tank and knows it's coming through the fuel pipe as I had to clip it
Fixed the swivel spring too
The last time it ran there was a lot of black smoke, it sounds right when you try to start it, oil is ok
I have serviced the carburettor, replaced the filter, bulb and the spark plug. It now start but dies within 10 seconds, do you have any ideas? I don't hear the fuel coming through when I press the bulb...Would not have been able to do any of this without this amazing video :-)
Thanks for this video, mines losing fuel and I will strip my carb. Any chance you can point me in the direction of the Gasket for this exact mower, I can't find one anywhere.
If you're losing fuel and there isn't any apparent damage to the fuel tank or fuel hose lines, then there is a possibility that the needle valve inside the carb isn't seating properly due to dirt. Your carb will need a strip down and a thorough clean. I had the same mower that's in the video. I bought a fuel shut off valve and fitted it between the fuel tank and carb. Simply cut the main fuel line and fit this shut of valve. Saves mucking about. As for the gasket you can get them on ebay as a kit. Just go on Ebay and type Sv150 carb gasket. You'll see a o ring and a gasket. You can also get the shut off valve on there as well.
Good job Paul some nice tips Got to go my dinner is ready lol.
Pete Froud hahahahaha nice one Pete
Can you tell how many litres of oil does a sovereign lawnmower take in litres thanks
600ml of oil
Hi, great video really helpful mine is also missing that little spring thing on the top that you wound back around to resolve the hunting issue, could you send me the link for purchasing, could not see it on your webpage
Thanks again
I'm looking for this as well!! Did you have any luck? Also the material washer that goes with it
Another great video. Would it be worth fitting an in-line fuel tap? They're only about £4 on ebay...
Shavenuw129 It certainly wouldn't hurt!
Yes. I had the same problem. The needle valve in the carb wasn't seating for whatever reason so I fitted a shut off valve. Never failed so far and that was 3 years ago now.
The point is as long as it works in the end , mixed views will always come ( fk people & there view point , you do a decent amount of work so deserve the reward 👍
Paul E Thanks Paul! I agree!
Did the Float needle have a little wire hanger?
Mine did
Just out of interest, whats the difference between the SV150 and the RV150 , I've often wondered?
Keith Miller I think the sv150 is fitted on the self drive models and Rv fitted to non self drive but i'm probably wrong? Good question!
@@MowerMan thats a good answer Paul, I'll have to check when I get another 150 and see if your theory works.
No still leaking a gooden :-(( I might bend it the other way and see if it makes any difference.
Run a bit of oil round the top of the dip stick o ring every time you check the oil ... it will always be free ...👍🏻👍🏻👍🏻
Geeman I did Geeman!!
@@MowerMan If that's not working try a dab of white grease on the o ring...
