BRIGGS & STRATTON 450 SERIES NO START

- 2018 Briggs and Stratton 450 series no start. This lawn mower was returned to Walmart, customer stated no start after very little use. We bought it "as is" non-running from the store manger for $20 reg price $150 new. In this video I will show you how to clean a plastic B&S carburetor, for this is the third time this summer I have seen the same problem. DO NOT attempt repairs in this video without a licensed certified small engines tech present.

Anyone who uses an impact gun on plastic deserves everything they get....
Hell yeah Taz man tell ‘em!!
Thanks for showing how to get the jets out! Mower started right up after a quick clean.
Thank you so much for this video.
When I brought the lawn mower out from the shed after a long winter (at the first sign of sun) I was troubled to find it not starting up.
To TH-cam I went, and your video I found.
I’d admit to being dubious as to whether your directions would solve the matter, especially I being a Brit and fear that there would maybe be a difference in my model engine to yours.
However, after just half an hour of following your advice, the lawn mower was up and running and I felt like a mechanical hero.
I doff my hat to you, sir. Thank you.
Many thanks from the UK my man. Your vid got the old girl fired up again 👍👍👍
I did this exact job today following your procedure and it started right up and purrs like a kitten... disappointed that Briggs and Stratton uses so much plastic for carbs.... great video
Pretty good Sir - however - inside the carb has the removable multi jet "thing" which is actually called a "cartridge". The center "tower" is removable and has Briggs' equivalent to an emulsion tube. In that tube are some very tiny holes which are used to emulsify (finely spray) the fuel into the air which then is burned for start-up and power in the cylinder. If the gas you put into the tank comes from a gas can the chances are high that you have picked up some junk from somewhere in that can and that junk is now in the fuel tank - then going to the carb. Those tiny holes get plugged and the fuel just stops at any time from FIRST start-up onward.. Absolutely will not start. Clean out the tiny holes in the center section, the other holes you mentioned and the top right angle hole. Filter the tank's fuel and use that to wash out the tank and fuel hose and then filter the fuel a second time to remove any and all junk. Then, if it's not horrible, return it to the tank, top the tank off with fresh fuel and away you go.
Carb or brake cleaner on the 'rubber' gaskets will expand / stretch them - and you will regret that (seriously regret that) at the worst time in the future.
If the mower still won't start then go to Steve's Small Engine Saloon site and research slightly opening up the right angle jet to .019 or .020".
Also, newer mowers with automatic chokes sometimes have a sticking problem in the linkage. Simple fix. Steve's site has a good video on that simple "drill-out" using micro drills by hand. - Joe -
Ok
This did help me, worked just like you showed. I used brake clean but seemed to work just fine.
Thanks for the help, no i can mow the grass. EASY, THANK YOU.
Hell yeah thanks for watching
Thank you! 🙏🏼I was ready to bring it somewhere but did what you said no it’s running like a champ. I gotta be sure to drain the gas at the end of the year
I'm doing this same job tomorrow....great video
Thanks...just solved my problem...super appreciate the video
Nice one, tried everything else, didn't work, but your solution, she fired up at the first attempt. Awesomes 👌
Good to hear! I'm here to share and help. thanks for watching.
Hey man. I followed your instructions on the video and got my lawnmower running again. Thanks!
a tip : watch movies on flixzone. I've been using them for watching a lot of movies lately.
@Toby Collin yea, I've been watching on Flixzone} for since december myself :D
@Toby Collin Definitely, I have been watching on Flixzone} for months myself =)
@Toby Collin yea, been using Flixzone} for years myself =)
I believe the problem is no fuel filter. I'm going to put a filer inline between carburetor and gas tank. Mine get dirt in it every 3 or 4 weeks.
Amazing Work
Thanks for reminding me of the starter fluid trick.
I didn't have any but shot in a 10cc measure of Acetone (nail polish remover) and my 450e kicked straight into life
I had bought and fitted a whole new carb, thinking that the E10 Bio-ethanol petrol had melted the carb as it did on another (much older) B&S engine
No. I'm getting old and stupid - I'd actually put kerosene in its tank instead of petrol.
I think they're made of plastic now because the E10 biothanol attracts water and then turns into vinegar (acid) Which would simply eat the die-cast Zinc they were always made of.
Plastic won't get eaten.
But anyway, if you use a decent fuel additive/preserver, it will attach to any water in your tank/carb and pull it through the engine and burn it before it accumulates in the bottom of the carb and does any damage.
Great video
I'm scared to take this apart but if it doesn't start tomorrow I guess I will try it. It almost starts does a big rev I think it will run goes for like 15 seconds and then it quits. Ughh Thanks for the video Kipp.
Thanks for watching, it may help to take photos or film record yourself disassembling the carburetor.
Much better vids elsewhere. The main jet under the float not identified, removed & cleaned. The other white plastic jets can be disassembled further (it has 2 pieces) to reveal the holes in the centre chamber which can then be cleaned and blown dry
Thanks for watching Mr. Brad!
Just like me, use a knife because we didn't plan ahead. Great video!
My pocket is my pry bar LOL! Just don’t tell parts warranty that. Thanks for you support.
So after replacing the spark plug, air filter, cleaning the carb and trying starter fluid.... What's your next guess lol? Still can't get mine started
Thanks for the video. Didn't think it would work as there was no noticeable clog in the jet, but it fired right up once I got it back together.
I’m here to help thanks for watching
Wow! Genius!
Your bottom jet is the main pick up jet , I drill that jet out to .025 with a # 72 drill bit and that will end your hard starting .
Thanks for watching
Thank you
Thanks for watching
Sooooooooo thanks for saving me $300 on a new mower lol. I will even SUB.
I’m here to help
So would it be the carb if it was running fine and just stopped when trying to add more fuel.
It wasn’t like it was sitting for a while prior
Most likely, spray started fluid near the air filter housing and if it starts momentarily then you have a clogged carburetor
why would a new engine need a carburetor cleaning to get running?
Poor fuel, quality, or corrosion or ethanol
I followed this video and others, cleaning out my carburetor 3 times thinking I just missed something, and it still won't start unless I'm actively spraying starter or carb cleaner into the carb while the engine is running. I'm not sure where to go from here 😮💨 I assume it's not sucking in the gas and just burning off what it being sprayed so maybe I need to replace the whole carburetor 🤔 idk
At this point I would cut your losses and purchase a new carburetor assembly off Ebay or Amazon.
Does anyone know what that tube going from the fuel tank to the air filter is? You can see it at 3:08. Mine spits fuel but I am not sure what to do.
Maybe it is some kind of an overflow valve? I'm also think about it
I think you’re talking about the breather/reed tube it connects to the hole on the side of the engine block and on the back of the air filter housing. It recycles fumes back to the air filter housing it also works as check valve. Let me know if you need further help. Thanks for watching.
@@dadsworkshopbykipplabrie7982 mine spits fuel. Primer button seems to also but mostly spitting out of that tube.
Someone forgot to attach the fuel line before they put the gas back in lol. It’s easy to clamp the fuel line and just slip the tank off the head with no tools needed. Gives easier access to carb linkages and carb 👍🏼
Yep you caught me
Kipp LaBrie just saw the little glimpse lol. Nice run-through on the job though 👍🏼
Like ‘at !
What do you use to clean the air filter soap and water ?
Compressed air
@@dadsworkshopbykipplabrie7982 ok do I gotta use oil on it or put it on dry?
It’s all gunked up idk if air will do the trick 🤔
No that only applies to foam/sponge air filters
@@dadsworkshopbykipplabrie7982 mine is foam do I put oil on it after I clean it ?
3:40
Did same thing, twice. No luck. New carb on its way, oh well...
Good luck..I've put 2 new carbs on mine and no luck on a cold start. Runs fine once it's started
Mine starts and runs on concrete but soon as i go over grass it dies....any ideas?
The governor spring is design to keep the throttle open under a heavy load/tall grass. Inspect the spring and make sure it has tension along with cleaning under the deck.
Did all that it started up exactly like video then went off and only started after sitting a while.
Great video but please don't do that with your knife tip, it's gonna snap the tip one day
Will do, yes it wasn’t a good idea thanks for watching
Life saver - Cheers
Will cleaning the carb as shown sort out a hunting issue?
No
Kipp LaBrie what do you suggest to cure my hunting/surging issue?
Adjust the governor/spring, make sure the auto chock throttle is fully open and not sticking and I would still clean the carb for good measure.
Tried this, unfortunately didn’t help, any other ideas? Mower worked fine, been idle for few months and now won’t start…
Check spark
@@rannz8 thanks, I’ve just ordered a new, no harm in switching out, fingers crossed
I can see you do not know how to change the primer bulb on that 450E engine either. Could you refer us to someone that knows how.
Briggsandstratton.com thanks for watching
Thats the problem the carb is plastic wow three times in one year everyone should just return the mower when its new and dont start and file a class action lawsuit nobody should ever have to do this with a mower that is less than a year old its not hard but a pain try to find a mower that is not made with a plastic carb
I just got a similar mower for free, With half the blade missing... No keyways sheered, But wtf?
You got lucky
Had to give it a thumbs down. You don't show how the carb is unscrew, the gas line blocked to keep the gas from spilling, etc. Then you don't show how you clean the jets! A lot of this stuff is intuitive but you have to assume that whoever comes here looking for advice needs to be educated on all phases of the process.
She runs lol
What a piece of junk. If you bought one of theese , take it back !
yeah , i just got one recently second hand , and yes it does seem like junk. Briggs and stratton are going tight arse like everyone else. everything plastic.
