Lawn Mower Will Not Start? -This is Probably Why! 'Simple Fixes' (by Craig Kirkman)

[@TheRepairSpecialist]

Hi guys I just wanted to Introduce to you my other Channel "Kirkman's Academy" - which i'm just getting started. It's a go-to channel for simple explanations for hard to grasp subjects such as physics, maths and chemistry etc. Here is the link: www.youtube.com/@kirkmansacademy/videos . Thank you so much for looking, and if these topics interest you then I hope to see you the there. Many thanks indeed. Craig 😊👍

After bragging to my new young sweet and beautiful girlfriend, that "I cab start anything in 15 minutes", I wasted 2 hours of adjusting everything to specs, changing condensator and breakers and not starting my 1972 MZ 150, that I knew, had been able to start easily, last time I touched it.. I ended up ditching the brand new NGK B6HS (as I reacall - at least the correct one) spark plug, and putting the old worn one back in, and succes.. NEVER trust a part, just bcz it's new..

[@MargaretPearl-fs6wh]

I have a electrical lawnmower that want start it was working I cut it off to get something out of the way want start back up I don’t know how to get the top off to-get to the motor

[@eventhisidistaken]

I love my dad, but one thing he did to me as a kid still kind of irks me. He had an old lawnmower that wouldn't start. I guess he had taken it to the shop and they said it wasn't worth fixing. So I asked if I could have it. My dream was to get it working again, and then use the engine to make a go-kart. A buddy of mine and I spent weeks working on that damned thing - neither of us knew anything about engines. We took everything apart, writing down how to put it back together, cleaned, sanded, borrowed a gap measuring tool to try to fine tune the spark plug (singular). I was into electronics and so I had a basic multi meter from radio shack that we used to confirm the alternator was working, etc. We got it purring - and then my dad wanted it back to give to a friend of his who was a perpetual 'ner do well and so always down on his luck. He basically forced me to sell it back to him for $5 - that was when the minimum wage was $2.50 and my friend and I had probably spent over 100 hours on it. ...don't know why I told you all that. Just needed to vent I guess.

[@kaylapilon8751]

I just took my step dad's old lawn mower that wouldn't start because he was going to take it to the dump. He does zero maintenance on anything he owns so i figured it would be worth a shot to clean up. I just finished cleaning everything and putting it back together. New carb, filter, gaskets and spark plug. Fired up twice and now won't go. 😂 I won't even send him a picture of what it looks like now. I feel ya!

[@008overrated]

Yeah things like that stick with you for sure, especially the fact that it was your dad. I wanted a mountain bike when I was a teenager, I asked my dad a number of times for one. He got me one but ruined the whole experience by reminding me forever that he bought me a bicycle. I wouldn’t mind but he spent most of his time in the pub

I've just got to say it. The metering jet is also often plugged with varnish in a float bowl type of carb. A little bath in lacquer thinner, carb cleaner or some other hot solvent, then a wire to ream the orifice will get you going.

Great video very informative especially for people who don't generally work on their own equipment. in my experience over the years most of the push mowers I come across will simply pull but won't start 99.9% of the time the safety lever cable is stretched or broken it leads to a small engine brake pad on the side of the magneto that acts as a kill switch its a $10 or $15 fix for a replacement and not to hard for the average DIYer to replace

Nice tips, thank you! I'll share that I had a hard starting Honda and only starter fluid would get it going. The problem was the throttle cable was mis adjusted and the choke was never fully engaged. After adjustment, it fires up with just one pull every time! It's a good idea to run a bit of SeaFoam fuel treatment in your gas to allow it to stay fresh and not gum the carb up.

Aussie fuel!!! Lol. Every few weeks fuel goes bad even with no ethanol. I find whipper snipper is a problem. I bought an Aldi one 2 years ago or more. It died just after warranty. Btw you have the good model. Briggs and Stratton with a metal tank. The plastic tank has an internal fixed mesh filter inside. A few times I have had to pull the tank off and empty it. Then back blast the mesh filter ( fixed type) with a compressor and the muck that comes out . Beautiful! This engine especially your model is the best. Excellent video!

Hi Pat. Either is good as long as you do one of them in my opinion. It will be good for the carb to clear it out of gas and introduce fresh into it as well though anyway. Thanks. Craig

Interesting topic, should also replace or clean the air filter. For me using fresh gasoline, cleaned carburetor I still need to use starting ether to get the motor running. Spray ether at the air filter, pull the cord, it runs well after the initial pull. I have changed the plug with no difference in a cold start pull. I also find adding isopropyl alcohol to the fuel tank smooths performance maybe indicating the ethanol in gasoline is absorbing moisture from the air new or old. Fuel stabilizer has not been a significant impact positive or negative but Isopropyl alcohol, aka gasoline antifreeze,5 has better results. In North America the red bottle of gasoline antifreeze at the store.

Have a lawnmower from the 1980s,I've never done anything to it in 25 years except add oil. Thing always starts in a couple of pulls. Even using 3 year old gas in it. My 4 year old lawnmower made mostly plastic gives me nothing but grief,no matter what I do 😆

some people use the anti fouling stuff you can buy at walmart. they say you pour measured amounts into the gas tank. but i just clean the plug and it works for me. after about 10 cleanings of the plug, i just go buy a new plug and continue mowing.

[@PainterD54]

The reason mowers don't start in the spring (as well as motorcycles, chainsaws and weed trimmer) is mainly because the gas has turned to varnish over the winter and clogged the carb journals and jets. Adding Seafoam in the fall will eliminate the problem and the engines will start up no problem. I've been using it for 20+ years and never have to work on my carburators anymore. (use it on your snowblower in the spring also!)

[@evelynbennett6435]

Never heard of seafoam. Is it sold in the US? Is it kinda like Stabilizer??

[@PainterD54]

Seafoam is used for a stablizer and to clean your carb as well as adding it to your gas to keep your carb clean.

[@philherrick7319]

Seafoam is petroleum distillates Good for cleaning fuel systems But Not a mechanic in a bottle Best to drain fuel and run carb dry for off-season storage

[@PainterD54]

@@philherrick7319 Ihave never drained a carb bowl for winter storage on any gas engine I've owned (I'm 69 years old) but I read about it being done alot. SInce I started using Seafoam many many yeas ago, I never had a problem with the engine starting in the spring. Just saying. And for problem solving when I first start working on an engine, I first run Seafoam thru it to help clean the system first, which 50% of the time actually works to get it running. Then I continue to clean and adjust. No Seafoamis not a "Mechanic in a can" but it is just a short cut to getting an engine running faster.

[@philherrick7319]

@@PainterD54 You have had good success. I stand by my comment (s) Where I live we have ethanol added to the gas at the pump. Ethanol is hygroscopic. BAD for carburetors/fuel systems. At the shop I work in we do hundreds of mowers/blowers, depending on the season. The majority of the work we do is fuel related. It's not only a question of using a product to stabilize fuel. It's also a question of cleaning the problems caused by the water in the ethanol fuel, along with unstabilized gas. It's BEST to drain the fuel and run the carb dry. That doesn't mean it always happens, however.

New mower last year. Failed to start in early spring this year. Checked the oil, air filter and spark plug, still no joy. Decided to drain the tank and carb bowl. Fresh fuel, started first time! The old fuel had stabilizer in it, which I was under the belief would help preserve the fuel over winter, but not the case. I'll drain the system and run it dry at the end of the year.

[@TheRepairSpecialist]

I'm really pleased you found the problem, Its crazy how fuel can go bad and how its overlooked. -Thanks Craig

[@timb7775]

Probably has to do with mowers having vented gas caps, not completely sealed off. And the carb isn't sealed off and vents.

[@SaxJockey]

@@timb7775 Yes, most likely. I read that lead free fuel lasts fairly well in a car tank, but not so much in a lawnmower (evaporation of some volatile compounds needed for good combustion). Exact same thing happened again this year; had to drain the mower and add fresh fuel; works fine now. I read that draining the mower tank and carb before winter might not be such a good idea, due to potential drying out/distortion of carb diaphragm/seals.

If the cord is hard to pull it's the key, or you have oil on the head hacheck for fire if you got fire it's your carburetor it needs to be rebuilt also if you turned your lawn mower with the carburetor down you may have oil in your carburation check the filter it maybe soaked with oil in that case, you will need to clean your carburetor. it's a good idea to change your oil too and sharpen your blade...

I have removed the carb, cleaned and replaced, new spark plug. I have taken off the fly wheel, the key looks ok and flywheel fits nice. How do you adjust the timing on this model. I have removed the head and looks like the valves are opening and closing correctly. Not sure wher to go next. keith

[@TheRepairSpecialist]

Hi Keith. Have you tried setting the valve clearences? I know you said the valves look like they are opening and closing correctly but if the valve timing is not set correctly you wouldn't be able to see this by eye anyway. I would start with setting the valve clearances. Then, if this wasn't the problem then at least you have eliminated the valves clearances and made sure they are correct. Good Job 👍 I hope this helps Craig

Near new mower use-wise that will only run until it uses up the primer fuel. Does not act like the ignition is cutting out it is like it gets no more fuel. The carb is all nice and clean inside and I have blown out all passages and they seem clear. All looks fine in every way. Gas seemed fine but I have drained out the tank and put fresh gas in it. Gasket and diaphragm sure look good. But could this be the diaphragm? Or any other ideas of what could have happened to this carb?

Debris in the gas is not my problem. I have a brand new mower. I put the oil in. I put gas in and when I went to pull start, it didn’t start. I took the top off and checked the pool start thingy, and it isn’t that. Cause the engine be froze from the factory? I need help. Thank you.

Hi. If your mower is Brand New then the best course of action is to take it back to the retailer you bought it from. That’s really unfortunate that you have this issue with a brand new item but it does happen from time to time. It will be under warranty but if you try to fix it yourself, remove items and possibly damage something then the warranty will most likely be void. Good luck

In the past, I bought three Craftsman for about 15 years. I had very hard times to start them, so I did not like it no more. Then, I bought Honda lawn mower and I love it. After three months without using it, I can start it by one pull.

pretty hard to beat Honda engines on anything.

I own a self propelled mulching Lawn Boy lawnmower, and it's very dependable, I make sure to burn off the gas in the tank by running it, before it's stored for fall / winter, and remove the brass bolt at bottom of fuel bowl and drain the remaining gasoline inside it, to help prevent gumming up internally. Also I've added a fuel filter to the fuel line going from the tank to the carb, and it keeps the impurities out of the carb, and helps alot to make starting easy in the spring, since the impurities are not entering the carb and impeding the fuel flow. Also the spark plug is taken out and check the condition of it, if its in good condition it is cleaned and re-installed. I got this lawnmower for free on trash pick up day, found out it would not start due to gummed up carb, cleaned it up, put new gas in, primed the bulb, and 1 pull it starts with ease every time.
