- Hey Everybody, B-rad here. Today I am working on my new to me Mantis tiller. I picked this up off of Craigslist for $20.00. I poured gas in and she just leaked out the carb. Ordered up a tune up kit on amazon for $15.00 dollars and installed it. Thanks for watching, hit the like and subscribe if you would like. Thanks!
Thank You so much for the video. I am a 66 yo woman , know nothing about engines, watched your video and got confidence to fix my tiller that has not worked in 5 years. And I am proud to say that it started after 2 pulls. I am ecstatic!
I got a 7225 model Mantis at a garage sale yesterday for 5 bucks. Starts when I spray starting fluid into it. Gas lines/carb all gummed up. Great video 👍🏻
Thanks for doing this detailed video. I am going to do this replacement this weekend. Your video helps tremendously
Glad it helped
Very well done. I completed the rebuild in about 45 minutes actual hands on time. I was working on a 7222 Mantis 2 stroke that had been sitting in a basement for 6 years. With that $14.99 plus tax kit I got an almost $400.00 (cost new) machine up and running. I appreciate the sharp focus and steady camera.
Yea, hard to believe you can get the whole tune up kit for so cheap.
Excellent Job and Video !!!! I will do the same on my Mantis. It's been in the garage for years. I looked at it today and the primer is cracked. I ordered the kit from Amazon. Thank you !!!!
got my mantis for 5 bucks at a local thrift store. it ran after a little cleaning of air filter and fresh gas. i just bought a carb and filter service kit. one of the tines has a broke off edge. not complaining though!
call Mantis--Those Tines are lifetime warranty,, Factory should send you new
Changed out my old carb today. Thanks man for a great tutorial! 👍
Hey B-Rad thanks for posting this great video. My Mantis is about 20 years old. Five years ago I tried to get it working to no avail. I had pretty much given up. I found your video and ordered the little parts kit from Amazon. $17.99. It took me about an hour and a half to clean up my dirty ol Mantis and get all the old parts off and the new parts on. My biggest challenge was the fuel tank which had old fuel mix in it that had gunked up in clods that were stuck to the inside of the tank. I fashioned a "q-tip" out of coat hanger wire, a piece of shop rag and a rubber band. With some patience and a fair amount of Goof Off I was able to get the tank cleaned out. Once everything was back together I fueled it up with some TruFuel. A little choke action and a pump or two on the bulb and it fired on the third pull! Works like new man! Thanks!
My 10 year old Mantis wouldn't start this year after working ok last fall. I saw this video, ordered off Amazon, and followed your video to a "T". Thanks! Mine started up right away. Couple of tips I'd add for other novices like me. If it won't start, check to make sure the gas lines are intact inside the thank. Discovered my old ones had got brittle with age and the one going in had snapped off inside the tank, so no fuel going in, no engine firing, LOL. Also, getting the new gasket to stay seated correctly so it doesn't slip down and block one of the screws to reattach the carburetor, is tricky. I solved by using two very tiny drops of glue between the gasket and the carburetor to set it in place, just be careful you don't put too much or put it to close so it spreads into the engine. Great video, thanks again.
Just assemble everything on the two screws before you reattach it and the screws will hold the gaskets in place.
Install assembly as a complete unit, very easy
Nice job buddy. Easy to follow. I got a kit a little while back to do the same, but haven't opened her up yet. Mine was leaking gas from the carb, too. Looking to do it this weekend. Your video was a good preview. Thanks for sharing.
Nice detailed video. Great focus job.
Thank you, good instructions.
Thanks for watching!
this one works great thankyouu
Very good video. I need to do the same to my 20 year old mantis. I was intimidated until I saw this vid. Now I know what to look for. I probably would have lost that little choke washer if I didn't know to look out for it. Gobs of thank yous man. Well done! What a bargain you got. All the spare parts were worth $20. Right!!!
Very g[d mechanic and great video I have to get someone to get mine going
Very good video you are talented more than me
Excellent job young man.
Thx man I’m going to fix the exact same model today if I can. I was told they are made my ECHO
I am fighting with one myself. Mixture screws are defying me so far. My other Mantis tuned ok with minimal aggravation. Waiting for another new carb and a base gasket just to see if I could have a defective carburetor, and or gasket issue.
Hey there! I wanted to Thank you so much for this video. I studied it a couple of times , took notes and ordered the tune up kit off of Amazon as well. I dove into the project today. Due to your video, I was able to complete the job in 30 minutes and the Mantis Tiller started right up!!!!!!! I am sooooo thankful:)
Have a Blessed Day,

Nice, just in time for spring weather
When it idles to high and the throttle screw won't adjust it Fon then you are running too lean on the low speed jet. Turn it out until the idle goes down. Then readjust idle screw and repeat the mixture screw if needed to idle and run/start as needed.
Hey B-Rad. Just watched this video again and paused on the sticker Koritz. That has the same sticker as mine but I can't find the model#. 5ehs engine family. I replaced the carb but need a throttle right side handle and cable. Thanks
Nice video - Good job!!
The hose with the filter goes on the bottonof the carb. the top one is a discharge line
The fuel filter hose with the in tank filter that sits in the tank bottom (It's important its new and present as they will partially plug and cause a fuel flow restriction that can make the engine run very lean at high rpm. A lean mixture will will damage it from lack of lubrication. if the engine revs then bogs its lean and this issue must addressed this can also happen if the high speed mixture setting is turned in too far or the low speed needle setting is set overall too lean as this impacts the transition from low speed to high ) is small diameter. The carburetor fuel "return" hose is the only larger diameter hose, its very hard to get them reversed but I have seen people manage to do so with a lot of effort as the filter pickup line is will not fit over the larger diameter upper carb return nipple on the primer bulb housing at the top of the carburetor, The third line goes to the white vent valve assembly that sits in pocket in the red plastic upper engine housing pointing up with the hose at the bottom , this is because the fuel cap on this tank has no vent on a mantis so this valve controls tank pressure and allows it to vent as fuel as drawn from the tank otherwise a vacuum will form and the unit will quit.. the tank is a sealed system that is supposed to be slightly pressurized when the engine is running the carburetor creates this pressure through the return line, if the tank is not sealed to hold this pressure the unit wont have proper fuel delivery so the fuel cap and fuel hose grommet must make a good seal that holds pressure..
I saw on another vid how they adjusted the idle with the tynes off. Until the crankshaft /axle barely moves then put on the tynes . Not sure if that changes the mixture.
Great little tillers except that the tines are always in contact with the ground. Big pain when tuning or just warming them up as it wants to move.
I know this is an old video but you can get a wheel kit for the Mantis so you can lean it back and lift the tines
This was worth every dollar you paid..I have one too.
I got one even older than that,after rebuilding the carb it has stripped gear box.
Keep the old grommet!
So my spark plug doesn't spark. Checked it, cleaned it, replaced it but no spark. I checked the Start/ Stop switch and wire to the magneto and those both work right. Anyone think it's anything other than the magneto?

OK there are two gaskets and if they arent on it will leak. I was hoping your vid would show where the small hole gasget goes behind the carb or facing the filter but you make the same mistake I did.
There's tubing or something connected to your gas cap underneath. Mine's disintegrated. Is that important? Also some gas mixture left in tank probably few years. What is best way to clean out the oily dirty residue? Thanks. Well done video!
On the gas cap is a plastic string that holds the gas cap from falling on the ground when refilling. Not important. The old gas just swish around some new gas in there and pour it out on some cardboard or paper towels and let it dry and then dispose of. Thanks for watching
I know this is an old video but you can get varnished up old fuel out of a tank with mineral spirits or paint thinner. Fill the tank with enough to submerge the sludge, or if it's really bad, fill the tank halfway, shake it up for a bit, let it sit for a while, and repeat a few times. If you have some marbles or ball bearings, or even some small nuts or rocks, it'll help scrub the sludge off of the tank walls. Long bottle brushes can be bent to fit into the tank and scrub odd spots as well
Thank you so much for the video. I was wondering if you could tell me where the kill switch wire attaches to the mantis after getting mine out for the season it has been detached from the motor?? And cant figure out where it attaches back.thanks so much
There is a connecter under the gas tank that then leads above the carb and into the top cover, looks like you have to remove the top cover where the pull start is.
@@BRadWilson3 perfect thanks so much
how to change an Ignition Coil on a mantis tiller as i think my one has had it can you help
Merci de vouloir le traduire en langue française et pour d'autre pays
I WAS WONDERFING WHERE THAT LITTLE WASHER GOES...OVER OR UN DER THAT LONG SCREW THANKS
I replaced the carb,tank, rope, spring,plug and cant get the tiller to stay running at idle. I started with both hi and low out 1 full turn then made minor adjustments out on both less than 1/8 turn. Spent over 2 hrs making small adjustments so I gave up for a day to clear my mind. Any suggestions welcome, thx
2 stroke carbs can be a little tricky to get right. Maybe try turning the idle up a hair. Then go from there.
@@BRadWilson3 I had the fuel lines reversed. The fuel intake should connect at bottom. I had it going to the primer bulb port. Was still tricky to get running. Thanks for response
Please always remove the tine assemblies before starting with a new or rebuilt carburetor. Sometimes they start at high rpm, so taking the tines off first is much safer. Good video!
First off you shouldnt have pulled the mounting screws out. If you had just loosened them enought to pull carb off you wouldnt have had to deal with choke and washer. Did you loosen screws before recording video. Yours seemed lot easier than mine were. Pretty good video though.
How can you pour gas!
Well I have got a mantis tiller it was running fine last year but now it just will not run its had a new plug carburettor spark plug I got a nw coil for it and what to know the gap to set and how to check the switch on it regards kevin best
To set the gap on the flywheel just use a business card in-between the magnet and coil. That's what I do at least. To see if the switch is working unplug it and check with a continuity tester.
OK thanks for letting me know OK
Use non ethanol gasoline if possible.
Yes non ethanol is the way to go in small engines. Unfortunately sometimes it is hard to find in certain areas. Only 1 station near me sells it.
Usually tractor supply stores like TSC and Rural King sell quarts and gallons, often premixed.
@@denonpmb Or even Home Depot for the Echo brand I use for my trimmer. - has the same company engine.

What are the exact turns out on both of the h & l please
To get a close baseline to start turn both H and L screws in till they lightly seat then back the H out 1and a half turns and the L about 3/4 to 1 turn out. Should get it to start then
So what is the “fuel filter” thing that goes up into the cover.
Hey B-Rad, would you happen to have the item number for the Mantis Carb. kit you bought from Amazon? I need the same exact thing for mine.
Thanks,
Jeff in Vermont
No I don't, I went by the serial numbers on the actual tiller. If I remember right, there were many different serial numbers( newer vs older models)
@@BRadWilson3 K54 I just put one on make sure you get OEM ZAMA on EBay for 35 bucks won't be disappointed.
It's in the video at 5:23.
Why does has come out of my vent ?
You probably need to replace it.
Nice socks & sandles
great job!!!
Should have wet the grommet with a thin film of 2 stroke oil before inserting the fuel line grommet to get an easier fit but also to form a semi wet seal between grommet and plastic tank..well I do any ways
