Old video but brilliant for the older magneto mowers. Had no spark - traced it back to an electrical connection I had made my self with electrical tape (from the magneto to spark plug)). This video was EXTREMELY helpful narrowing down my problem. I had used electrical (plastic) tape which is normally OK BUT heat from the the mower engine had caused a chemical reaction with the metal connection and electrical tape glue causing problems. My mower was a throw-away (was in the rubbish when I found it) and the previous owner said it just wouldn't start. Cleaning the magneto metal base posts as per this video was a big help too. I used a multi-meter inline from the magneto to the spark plug to check for spark. Replaced gooey connection I had with a metal connector. All good. THANKS for VIDEO!!! Really excellent! Luv my old mower !subscribed!

[@lepabrena78]

Doublewide6, thank you for this video! My husband got out to mow a overdue lawn, well, lawnmower would not start! After messing around, cleaning, checking, I find this video and saw how you tested the spark plug without a tester. We changed it and he is mowing it now! One thing to note, for us dummies, ha ha, make sure you make contact with the metal, just like you demonstrated, or you will get shocked. Thank you! Love youtube and nice people who like to share ;)

[@anthony851]

We inherited a near new mower when we bought a house that did not run. Removed the kill switch wire off the coil and eureka! Hi from NZ, Anthony

[@johnmcewen3022]

Doublewide...thanks for your small engine videos. They are the only ones that are really comprehensive. Trying to learn the business your videos are invaluable. Please keep them coming!

[@danielcornwell6563]

Excellent video. Probably one of the best how to videos I’ve ever seen. Very thorough.

[@shannonkepler799]

Thanks very much. Was having problems getting no spark on my mower and thanks to your video I was able to diagnose a bad ignition wire. Saved me getting slapped with a maintenance bill at the mower shop 👍

[@petegeeding893]

Thanks for the help I grew up with a dad and Uncle that worked on small engines for extra money so that was 40 years ago and I forgot alot of it. Your video helped me remember alot thanks!

[@otisbrown1997]

Thanks!!! I was ready to junk the riding mower, I tried EVERYTHING, until I filed the two holes that hold the coil to the block, riding mower started on the first turn of the key (scared the hell out of me, because I wasn't expecting it to start)

[@jmobaldwin]

this was super-helpful. I took my mower apart, disconnected the kill switch wire from the coil and it started right up.

[@TopNotch50]

Replaced the coil and still no spark. While reviewing this video, I filed down the perches the magneto mounts to, and voila. Thanks for the tips!

[@edclark1119]

Thanks for the video. Pulled my coil, took pics of the model number, filed the mounting post, started right up.

[@Callimotz]

Nice tip about filing the posts most people wouldn't get that its kind of like cleaning the battery posts and clamps on your car. Keep connections clean parts will last longer. Bravo

[@cland20603]

An extremely knowledgeable video-you have saved me alot of time and hopefully alot of money. Many thanks.

[@squarehouse5918]

Thank you very much for the explanation.Disconnected the kill switch green wire and mower started. Temporarely and until the short found, I installed a waterproof ON/OFF switch on the green wire to shut off the mower. Thank you again.

[@DJClausUSA]

Thanks, great video and very helpful. I just disassembled the coil and assembled again the same one with the business card gap adjustment and the mawer is running now fine.

[@restez1963]

Hey thanks f\to people like you for taking your own time to post things like this to help others. i was given a $500.00 lawn mower because neighbor said did not start because of you bad coil. i sold it on craiglist $350.00 thanks so much

[@vw66bus16]

Thanks for the video. My "no spark" was due to the shut off arm not pressing the kill switch enough, thereby it was always in "kill mode". Fixed it with part of an ink pen. Pulling the kill wire as suggested produced spark so i knew where to look.

[@paulstir]

Great video very clear instructions , I have the same problem at the moment I will follow the instructions thanks 👍🏴󠁧󠁢󠁳󠁣󠁴󠁿 it’s great to see your family made it and that they are healthy n happy

[@deacontravel]

Thanks for this video. I had cleaned the carburetor, gas line etc etc and it still wouldn't start/spark. After watching I removed the cowl and realigned the coil and now it starts first pull. Thank you for ending my frustration.

[@c.s.4845]

Much appreciate the walk through fixed our lawn mower with it!!

[@pcosta24]

Good video. Nice family. Enjoy- they grow fast.I had to replace the cutoff cable. When I put the brake bracket back on I must have left the wire in a bad spot probable rubbing on the flywheel and slowly wearing off the insulation on the wire ( it was a bear to get that brake assembly up in under the flywheel.)Maybe there is a trick to it but I never did it before. It ran for about an hour and then quit. No spark on plug cleaned everything, re gapped it . Still no spark. I looked real good and saw the wire had been gouged and must of been the flywheel and the wire was bare. I fixed that with some solder and shrink wrap. Still no spark. Do you think the bare wire shorted out the ignition module because there is no spark on the coil now? Is there a way to ohm out a module? Also thanks for taking the time to make the video's and have a great day!

[@gmoney7000]

09/30/2021 ,Thanks for saying something about that kill switch wire because I was thinking that was a power wire it is 2:27 a.m. right now but I will be trying it doing daylight hours . This is the only video I seen I want KZbin that explain that Kill switch wire on KZbin. Thanks a lot 09/30/2021 @ 2:27 a.m. .

[@dgb56bgd]

Good content. Congrats, you did it. Very educational. Thanks and Blessings to you and your lovely family.

[@bflotim]

Great video, thanks! A quick suggestion for your one handed situation, get a tripod, lol!

[@DivineMisterAdVentures]

THANKS for reminding me I have to ground the plug to see a spark! Problem Solved! (Or at least on to the next step!)

[@danhanks1]

My mower is starting again, thanks for this video!

[@paull4968]

Thanks. It was the kill switch that was not working. So fired up the mower with the switch disconnected and bam! It worked. Just found that the part clamping the cable down broke and tied it down with a clamp. All better.

[@doublewide6]

paul l I'm happy the video helped.

[@charlesmartin7347]

doublewide6 Yeah buddy you got me you made it so simple and you have me access to the the parts. Great job and beautiful Family. God bless you and your Family

[@charlesmartin7347]

doublewide6 Thank you for sharing your knowledge I appreciate you God bless you and your Family you made me look smart in front of the Wife again I was losing ground. 😉

[@garylandry2638]

THANK YOU ! FOR THAT DEMONSTRATION WELL DONE !!!,THIS WILL BE A HELP TO OTHERS !!!!!

[@cleveaaj]

Well explained and good pointers especially using the business card for coil positioning.

[@georgebarr2123]

Thanks for the tips. Mine just died and no spark I know what to look for now. Thanks from West Australia

[@kitwintour9600]

also try cleaning the coil with a rotating wire brush it works for me and clean the fly wheel magnets this works too

[@yongminhuh146]

We will do! Thanks!

[@doublewide6]

Did you replace the coil and fix it before you sold it?

[@waltszpunar9721]

Great help with this. Thank you. The video is clear and process well explained. I implemented one more thing and that is to put liquid soap in the sleeve prior to wire R&R. This helps the old wire slide out and then the new one inserted into the spark plug protective sleeve. No need to split it open. I then used a can of air duster to blow out the moisture.

[@Gil3089]

Great vid! Thanks for posting, I was about to buy a new mower till I seen this vid and noticed it was a short in the kill switch!

[@juicer52]

before tearing into this, I moved the kill switch wire and it started right up. I will dig further to find the point of a bare wire for a permanent repair when the temps drop around here.

[@MendezField]

If my lawnmower disk rusted will it affect the spark

[@jetafel]

Thanks for the info. I was pretty stumped, but I just got my own mower started after following some of your tips. Great videos!

[@MrEldonus]

Thanks for the good information and easy to follow presentation.

[@travieso1208]

Great video, very informative. Thank you.

[@donb1183]

Beautiful family! Thanks for the video, easy to follow and useful.

[@vladmircea3174]

You are awesome for posting this. Thank you so much sir❤

[@3079daddy]

My thoughts and prayers for your son. I hope he gets better soon. Thanks for the video. Did I hear correctly, rust on the coil or magnet on flywheel will not make any difference? My mower starts when cold, but shuts down 3-5 minutes later. Thanks!

[@patcrowe4991]

3079daddy

[@glennliang]

Thanks ! I have the same trouble on this model. right now I think I can fix it.

[@gerardsagliocca6292]

Approximately how much was the coil ?

[@d.j.russell6019]

Changed spark plug, changed ignition coil... Craftsman 5.5 .. Runs when I disconnect green ground wire from bottom of ignition coil. Checked Brake assembly and no wires broken .. just not sure what the brake assembly should look like and what wires should be touching what... perhaps a contact is not sitting correctly?.. Can't find diagrams online either.. Any ideas?

[@KirchTX]

Thank you Thank you Thank you! I actually had a bad kill switch. I thought.. there's no way this is it, but let me try it. Boom first pull!!

[@Jocy9111]

Do the valves have to do anything with no spark?

[@MrDondoerner]

Will you get a shock testing the spark plug?

[@KDOGsDomain]

A very informative video, and a great looking family. Thank you. :-)

[@andybridges8813]

Hello, I have a Tecumseh engine on my mower which is a Champion Self Propelled 46cm. I have a spark and I have taken the carburetor off and cleaned it. When trying to start it it occasionally 'fires' but won't run for any length of time and also floods the spark plug. Is it possible for the coil or the spark plug to be breaking down under load? I've tried another spark plug (second hand) and the problem is the same. Any help would be great. Thanks

[@mountainbiker44]

I had the same lawnmower. Where can I buy a replacement Gas tank? Thanks

[@treyshomo5783]

I have a John Deere ant 622 gator with no spark I replaced the ignition coil twice and the spark plug multiple times still no spark any suggestion thanks

[@bryanbyrd9770]

I've done everything recommended, certain I had it under control. New coil, .009 gap, new spark plug, filed clean the mounting posts, handlebar actuated kill switch seems to open and close as per a continuity switch - probe on flywheel and on lead to bottom of coil had continuity when the handlebar lever was in "shutoff" mode, none when bar was in "on" position. Still no hint of a spark. Guess next step is remove the flywheel? Haven't tried running with the ground wire disconnected. What is next?

[@bryanbyrd9770]

+Bryan Byrd To possibly add more value to this valuable thread, two full frustrating days and $85 later, a lawn mower shop determined the coil provided by Sears was not any good, and he put in a used one and the mower runs fine. Sears claims the part number 440505 is the right one for engine model number 143404162, but I never had a single spark. Maybe it was defective? Good luck., and thanks doublewide.

[@wilfredheggart8394]

hi double wide six wat should i do to get a push mower going that starts wen you put gas in the carb please help my old mower blew up on me?

[@twiddledeedom]

great presentation will try tomorrow !

[@wjackstl]

how are interchangeable are those coils? I've got an old one from an old mower, can I use it?

[@HandyTim]

Yeah

[@UtwoBed]

Is there a way to test the coil with an Ohm meter.

[@coreygorr5869]

worked perfect! Thanks very easy to do with your explanation

[@doublewide6]

Corey Gorr great to hear. Thanks

[@virgilwhite3074]

I have no spark in my craftsman riding mower. I have replaced the plug and coil. I also took off the flywheel and cleaned everything. I seen the stator was burnt on 3 coils so I replaced it too. The previous owner said he was driving it and it just quit - he tried to rewire it and I think he left the voltage regulator out and that let him burn out the stator to my opinion. Now back to the spark plug spark. I did clean the ignition coil screw holes. Took off the kill wire from the coil, used a business card for a gap and still no spark! I am lost at this point besides thinking it may be the magnets. Any ideas???? No doubt the magnets are not dead in total. How do I check/replace/recharge them??

[@traviscovington4508]

Virgil White what was your issue im having the exact same issue?

[@yvonneo5360]

I replaced my coil on my old riding lawnmower. I was getting no spark before. I still am not getting any spark. What do I check next? HELP

You win,AGAIN. See below.

[@gobloit4473]

Wheres the other end of the kill switch wire go?? :/

[@GeneralG1810]

Just follow it you'll find it

[@briant3403]

those magnetos get rusty it will not start, we had to sand the ends and flywheel off on 5hp briggs, this gys a backyard hack

[@user-sp8eb6iz7f]

Don't you get shocked handling that wire?

[@doublewide6]

scoremx mx Not if the engine is not running.

[@briant3403]

why do you people make videos,or half ass video when you cant set camera down

[@fishinjunky]

doublewide6 - first off, hope you son is OK. Just viewed your video about his cancer. Prayers to you and your family. If you can't get to my video I understand. My mower has no spark. replaced the plug, no spark. replaced the magneto by following your directions, and still no spark. thoughts?

Hey, thank you so much for this video! Especially for a tip about disconnecting kill switch cable and giving it a try. I was able to fix my lawnmower by simply adjusting kill switch connector and a bit of polishing...

[@unionbetty]

Thank you,thank you and THANK YOU I followed your instructions to the letter and now I'm mowing better than ever. You saved me the cost of a new lawn mower. ( not that I wouldn't like one ) I plan on watching more of your videos.
