This FIXED my mower! I had a small break in the insulation of my kill switch wire. Getting in there with the help of this video showed me the problem! Thank you Mower Man.
Tim Armstrong Marketing Top work Tim!!
All the trouble that i was having getting it to start, taking it apart many times putting it back together it was my kill switch the whole entire time ! Thank you for your help !
Glad to help Raymond! Glad you got sorted
This was perfect. Thanks for posting this.
Thanks mate. It really does help this kinds of videos. Cheers.
Excellent explanation. Thanks a lot.
No problem

David Hoag you are more than welcome. Thanks for your kind comments
@@MowerMan Yard Machines 21" Push Mower - 11A-B0BL700 ..start at first pull....can't stop . need to pull spark wire to stop..how to fix?
At about 3 mins, the kill switch pictures were not very clear to me but once off the machine I saw there is a 'ramp' on the brake mechanism and the 'switch' has a bent end which is supposed to ride up the 'ramp' to make a connection. Releasing the brake breaks the connection. Once I understood this, a good cleanup of the touching surfaces and a very slight adjustment to the 'bent end' brought instant success. To think of all the wasted time checking the plug, coil and connecting wire! Oh dear but thanks for the inspiration to have a go. BP
Thanks for detailed explanation. Great!!
Excellent mower man thanks
very informative, thank you...
Good job!
just what I was looking for, thanks !
In my case the switch was just oiled up, a blast with some brake cleaner and an old toothbrush did the trick, stops dead now. Many thanks.
PERFECT. Thank you so much.
Brilliant, Thanks Mower Man! Problem solved thanks to you :-)
G Allport Glad to help
Good info, I have a starting problem that started when I broke the kill switch cable. I believe this may be my problem. The video helped me but it needs to be a clear picture, it was a little blurry.
I took a look after scratching my head for weeks, not wanting to take it to the repair
shop .. and sure enough it was the break and that wire that wraps around... Thank You So Much for Posting!
Informative video. Thank you.
thanks
Thanks for the valuable information mate!
Any time! Ahmed
hey thanks your video helped me so much .............
I also tested all wires and they are good
Thank you so much this video really helped me, now I won’t have to keep shocking the living daylights out of me trying to remove the spark plug cover! 😁👍
I’ve watched a lot of your videos and they’ve all been really useful as I have a absolute nightmare of a mower lol
Hitachi 42 inch TVs are power consuming monsters haha!! Excellent news! Glad to help
Great video thanks. Can I bypass just to check spark? It’s only happened since it broke the cable? Thanks
Great video... the problem I was getting was the lawn mower just wouldn't stop
You did an excellent job describing all the problems this switch can cause and remedy, my friend. Thank you and g'day to you.
Frank Besek Thanks I appreciate that!
Ty it greatly helped informative and problem solving...great video work to
Thanks Roman!
thank you. Such a clear demonstration of the switch.. I would like to know how to test the wire integrity.
thanks
Arnold Bullock If you get spark the wire is fine
thank you .... you are a life saver
steve morris No problem! Hope you subscribed!
Thank you muchas gracias
Thanks I fixed my mower with your help it now works.
What did you do to fix it?
@@samirsharda7895 pulled the wire out of the kill switch
@@michaelhodges4331 And did you keep it out?
@@samirsharda7895 yes
Top banana!
I got an older mower i think where a green wire goes under the flywheel. Touch the cable stop or ground the green wire should stop it but its not. What does it attach to under the flywheel?
Hi, Mower Man hope you your well,
please can you help me? I have the same mower as you have in this video 22-inch self-propelled mower with a 4.5 Briggs and Stratton engine,
my brake shoe as come, of completely can you help, can I just simply just use griller clue to stick it back on or will I need to replace it completely if so where can I get one from in the UK,
thank you in advances,
On my lawn more the brake pad has come off. Where can I find replacement? Hawksmoor XSS46F. Thank you
hello, very nice video. I own a briggs stratton mower and it was working fine, half way while i was doing the lawn I started the engine but now when I hold the throtte to start mowing the engine is at full speed and it very hard to control it, if i tried to leave idle it will stop but at full speed its not only dangerous but also hard since it vibrates a lot. any suggestion on hot to fix this??? thanks in advance
Hi, one of my bolts snapped off when I was trying to remove the kill switch assembly. Can I run the mower without it? I have another similar mower that doesn't have a kill switch. What do I need to do with the wire from the coil ? You said it is needed to get a spark. How?
You are the man!!!!!!!!!!!! THANK YOU SO MUCH, WATCHING THIS VIDEO MAKE ME REALIZE THAT MY KILL SWITCH WAS ALWAYS ENGAGED SO THE CIRCUIT WAS ALWAYS TO GROUND!!! FUC**** YEAH!!!!! I NEVER REALIZE THATH The handle mechanism when you move the lever, the little blade never disenngages ground!!!! I remove the wire from the switch and there you go ! STARTS AGAIN!!!!!! THIS WAS DRIVEN ME NUTS!!!!!!!!!!!!! I check everyting, thousand times but never the kill mechanism. SO BASIC CHECK!!!! I even change the coil and the spark. Thankssssssssssssss!!!!!!!
Javier Cerati Glad I could help haha!!!
Hi, my briggs and stratton mower the same as the one in this video, used to start first pull from cold after 3 primes, but now it does not fire at all after 3 primes first pull, but starts after 2nd pull ? this problem started after i changed the oil, it was the proper oil B&S sa30 after tilting to get underneath to remove plug, but i didn't run mower to heat oil before draining old oil, could that be the problem ? any suggestions please ? i put on a new carb diaphram and gasket. thanks Bruce
very good video
TomJohnson121 Thanks
Hi it sounds like the governor flap assembly is suck open or one of the springs is missing.
Thank You SO MUCH! i feel smart now. =] peace ~*
hello, i have the same engine as you do....and i have a big problm and i do not what to do...i am repairing an old lawn mower and it was ok , when i start the engine, motor is running perfectly and after stopping it by killswitch, want to start again....maby, perhaps i have a wrong ignition timing and spark apears in the wrong time and motor almost explode... how come and what is happening ...please help me
So this works because you are removing the fixed ground from the block and relocating it to a ground on the handle to a intermittent ground right? I have a Troy bilt mower I am wanting to do this with and still learning how to work on small engines
Te felicito
Hi, my 3.5 hp briggs and stratton with pulsa primer, when it starts white smoke comes out of exhaust but stops after about 5 seconds ? could this be i need to replace the piston rings ? also it seems to have lost a bit of power ? it is 9 years old and has never had head and inside de carbonised ? would this help power if i de carbonised head ? Thanks :)
I found a broken wire which I believe ought to be connected to the coil . But which part of the coil to hook it to?
Hi I can’t pull the handle on the throttle cable seems very stiff any ideas how to make it loose
My kill switch is will not move at all what should I do take it off or check for something else.
Great video, I’m having trouble where the push lawn mower won’t turn off after I release the throttle cable, the mower keeps running. I check the kill switch assembly and it’s making contact when releasing the throttle cable. What do you think the problem? Thank you
kalamelliel I would replace the wire that runs to the ignition coil from the kill switch
FUCKING FINALLY. I typed “self propelled wiring diagram” 3 hours ago, nothing but riding mowers
Question? Have a kgro 4.0 hp push mower by k-mart with no spark. Replace the coil and plug still no spark. Shave the rust from the flywheel and again still no spark. I even disconnected the kill switch from the coil itself with still no spark. Any suggestions!🙄
Not sure tbh. I'd check the flywheel key though
Is there a link to purchase the kill switch
I don't know about the kill swtch but today Jack and I fixed the throttle cable. It no longer worked. Jack cut throttle cable and replaced it with an 8 inch cable. Hé shifted throttle plate to 3000 rpms with an 8 inch cable...screwed it tight and it runs perfectly. He overrode throttle cable entirely. Infact we just cut it away. I was not convinced! Just jerryrigged whole throttle assembly. It purres. Amazing. He can just look at a small engines and figure out a fix.
I never thought about that fix. Couldn't have dreamed about it. I just have to rake his leaves and winterize his yard as trade.He does brainwork. FIXES my old lawnmowers. All trade no money.
He is a genius on 4 cycle engines. It took us 2 hours to figure out a fix. I was flummoxed. We froze, but he pontificated it with coffee and cigarettes and he figured it out. Amazing!!!

David Weum Top work David!!
Learnt a lot from watching the DVD in its entirety, great tutorials. Where can a I source a replacement kill switch (396847) for my B&S Classic 35 here in the UK?
Hi Graham thanks for that. Try a website called briggsbits.co.uk briggsbits.co.uk
Thanks for the prompt reply. Have sent a request to Briggsbits.
Super vide
By far the lawnmower videos
You should return to making videos!!!!!!-
How do you find torque settings for a mountfield HP 470 mower.
Is there a website with service information many thanks.
No idea I just bolt it back on and never have a problem
Hi, Mowerman, love your videos. Could you do a video on resetting the timing on a Briggs mower? Thanks.
Mick Humpage Hi there this is a video on that. Also check the top flywheel key. If it's damaged at all replace it. What's the problem you are having?
Mower Man, thanks for the reply. My neighbour left me a mower when he moved house, very poor state. Compression was good but started for a very short time, pull cord ripped out of my hand first, backfired and died.
I removed all the coverings learned from your videos. I had seen some videos on removing the flywheel without using a puller, I replaced the key, tightened down the flywheel. The engine run for approx 1 min made a clattering noise and stopped again.
Mick Humpage what mower was it? If it has valves that you can set like ohc it could be that. Take a look on my channel at the honda videos on how to set valves
My engine fires up after priming then cuts out after the fuel has burned. The carbs clean as a whistle and it's new fuel. Can anyone help please.
Hi mower man. Can you tell me the cause why my riding lawn mower back fires when i shut it off after cutting ? Thank you for your help.
Raymond Hoagland I really have no idea i'm afraid!
@@MowerMan Thank you !
Hi Mower Man, can u show me How to unlock the brake on a riding mower??? thanks Big Mike in Oregon
What if the lawnmower over speeds? I have checked and replaced the springs under the air filter, but that didn't make any difference.
Try a different belt
Hey Mower Man! I recently purchased a 22-inch self-propelled mower with a 4.5 Briggs and Stratton engine like the one in this video. My bale bar was extremely sticky and the mower doesn't shut off when it is released. Although the mower starts and runs (stuck on lowest idle, will replace throttle cable soon), I removed the small kill switch that you said could be removed with a flathead in the video. However, I was wondering if the small plastic piece can be reinstalled? After re-installing it, my mower doesn't seem to start.
It could be that the wire doesn't pull tense enough to allow the mower to start? Any suggestions? Should I disassemble and install it again, or do I need a new switch?
look for the vid on how to replace a kill switch and make sure it dis connects properly
@@MowerMan Thanks. The carb, air filter, spark plug, and everything is to order.
Is there any other reason the machine cant start?
Thank you very much for this great video. I would give you 10 likes if I could. I was able to press the tab and move the wire as you said and get my push mower back in service. I am very appreciative!!!
Thanks a lot glad I could help.
My lown mover not getting spark , might try this
Change the plug first and check the ignition coil wire isn't split. It's rarely the kill switch.
@@MowerMan thank you I will do that and come back to you to let you know how it went .
@@MowerMan checked f7rtc spark plug for ferrex 18" 141 cc lawn mower was showing 18.78 ohm resistance when set at 20k on multimeter
@@MowerMan I changed the spark plug and crank shaft pin , now it's working as good as new . Thank you mower man .
Ahoy ther this video is 3 years old um are you still on this channel ? Just want to say thank you for giving me the idea of the kill switch I have a my son's friend grandmother's 2007 150z snapper zero turn. With a 20hp Briggs & stratton it's got spark to the wire I sprayed starting fluid in the breather erea but still not want to run any more tips besides the kill switch. ?
Set the valves. See donyboy channel on hard to start rideo on mowers
I just checked the compression with a tester no compression now my lawnmower quit on me 😞 I'm on a low SSI check each month barely can afford gas to take my wife to chemo treatment 4 times a month we're in our late 50s she has to take chemo treatments for the rest of her life her chemo therapy is 2hr drive one way 😞... Is there any tricks for no compression on this 502cc 20hp briggs & stratton 2007 model ? 😞
@@johngray2526 make sure piston hasn't snapped first.
@@MowerMan that's my next step is going to go pull the valve cover & the plug back off & see.
Welp the piston didn't but I was able to push it back down it went down smoothly tho so what's nexts 😵 lol
where ya from?
👍 (🇺🇸Sub'd)
can you by pass it
Help i tried everything... new spark plug ...new coil... lawnboy turn on when kill switch is not installed. But i cleaned and messed around with the kill switch manualy and still doesnt make a spark. Also checked coil gap im at a lost
Your coil is good it is your switch
@@bloodbrotherinjesus9906 fixed it. There was a green wire plugged into a y connection linked to the kil( switch. I disconnected the green wire and now everything works normal. The kill switch was fine
Excellent video....but difficult to understand...but I wish....he spoke English...har har har..
Not helpful. My mower has three terminals, as it's a gas mower with the electric starter motor
Great video thanks. Can I bypass just to check spark? It’s only happened since it broke the cable? Thanks
