Alright so today on Repairs101 I need to throw a quick service at my old lawn mower and so while I’m at it I’m going to pull the blade, sharpen it and check it for balance.
I bought this mower at Walmart back in the Y2K for about a hundred and twenty-five dollars.
OK so the first thing you want to do is to remove the spark plug so it cannot possibly start. Take some Brake Clean to the area around the crankcase’s oil filler port. Remove the sump plug and drop the oil. After that, tip it on its side so that the carburetor is pointing up. Then put the drain plug back in and clean it up to your taste. Me, I’m not going to be too fussy about it. I may have to paint it next time.
I know not everyone has access to a bench grinder so I’m going to do this one in my vise. You don’t want to spend too much time fixing one of these blades up, considering it’s only about twenty dollars for a new one. Get it as clean as you possibly can and protect it with some oil.
This one has a few nicks in it but I can file it back with a single cut file to get rid of most of the problem. I’ll do fifty strokes on each side and then check it for balance by hanging it on the end of a screwdriver. It’s a little heavy on the left so I’ll just file a little material off the end and check it again.
Make sure you know which side is which before you bolt it back on. I like to use a little Never-Seez on the bolt and on the flange face. When divided by twelve: that’s fifty foot pounds maximum torque.
Now is a good time to finish cleaning up the motor. Too much dirt will insulate it and make it run hot. Rinse out the air filter with a solvent or cut a new one with a synthetic sponge.
Now, if there’s no dipstick, like on this one - you’ve got to fill the oil to land in the range between the bottom of the thread cut-out and the top of the thread cut-out.
This is the original spark plug and it’s already seen fourteen seasons of mowing - so obviously I’m going for the record! Check the spark plug gap before reinstalling it.
Happy mowing!

Down to earth basic advice on how to make your mower last for years. Might have included to run out the gas in the carburetor at the end of the season. Great video!

[@repairs101]

Great tip!

You have given me the confidence to give it a try, what's the worse that can happen when smoking the grass

[@billruland1494]

Loved the mower repair one! While I have done the work myself beforehand, I never thought to file the end of the blade to balance it. Thanks!

[@repairs101]

Glad I could help! Thanks for commenting! (and happy fishing!)

Thank you for the video, my grandfather has had his lawn mower for 25 years, he never changed the oil or spark plug since it was new, so today for the first time in its life, I changed the spark plug and oil and boy the oil smelt so bad I almost puked, and the spark plug was so fouled I was surprised it had been running all of these years, so I put a new plug in and I changed the oil with 10w30 even though it recommended sae 30, and boy does it sound so much better lol, I even sharpened the blade and made it balance and it cuts so much smoother

[@willienillie6337]

Excellent video. Need to do some service on my mower.

Aidan Gribbin Thanks bro.

[@robertmunguia250]

Is that with muffler side down or up? When you tip it on its side?

[@bgrady24]

I tried all these tips, but I still have a matchbox car stuck inside my ass.

[@4451ab]

I enjoy all your videos thanks for posting

[@MrFERENGI]

thanks. just been given a mountfield mower and couldn't start it, thought it was broken

[@akbaxb165]

Learned a lot within 3 minutes of this video. One question though: would you use 5W30 Synthetic instead of SAE30 oil for this lawnmower. Thanks for your help in the matter.

[@repairs101]

akbaxb165 The service data sticker on the side of the mower ( 0:19 ) says 30W and I always go with the manufacturers recommended fluids and fuels for any machine.

[@wrongmower]

Made a hundred bucks plus parts for two mowers last week in my neighborhood :))))

[@repairs101]

Something to do with your alias, Wrongmower?

[@wrongmower]

Lol, kinda sorta

[@Na5iR11]

As are you.

[@VirberelloScooterTips]

Thank you for sharing your video great information :-)

[@repairs101]

Thanks for commenting! (everybody wins!)

[@willienillie6337]

Why does the carburetor need to be pointed up when tipping to the side?

[@repairs101]

Otherwise the fuel spills out.

[@uhhh684]

when you are filling the oil and there is no dipstick what you said will apply to all push mowers right

[@repairs101]

If it looks the same.

[@uhhh684]

@@repairs101 I'm sorry, if what looks the same?

[@kateryder530]

Hi, the lawnmower was turned on its wrong side with the oil inlet uppermost to clean the undersurface. This caused oil to come out of the air filter. The lawnmower now won’t start. Someone suggested emptying the oil out of the machine and pouring petrol down the exhaust in an effort to try and clear out the remains oil. Is this right? Thank you

[@repairs101]

Messy but probably effective. I would use compressed air and/or brake clean.
