I had to rebuild my nikki again at the seasons end. The float was way to high even with new parts. So I heated the float to make the float seat level with the bowl housing. Now the engine runs great and super smooth. Thanks for the video fella too.

[@dougbrazell5407]

I have the same lift table you do and I added a 2x6 board to each side and I can lift riding mowers with it now . it works great. love your videos.

[@josevasquez8193]

Very helpful - really liked the slow pace of all the steps.

[@ChaosAttractor13]

I cannot thank you enough. You are an angel. I was brought to tears this week trying to rebuild my carburetor. I can’t find a how to manual. I still can’t tell if the main jet was put in washer first or jet first. I have a 50/50 shot. Thank you for being better than everyone else. You have my like and subscription. Please keep up the DETAIL ORIENTED instructions coming.

Thanks dude great video. I took apart a nikki carb from the used snow blower I bought and I am feeling a little anxious , the blower was running fine but I needed to see inside that carb and clean it up , I hope I can get it back together right , your video really helps a lot.

[@Redgascan]

Thank you. Great information.

[@biopellet]

very thorough, better than the rest, good job -thanks!

[@justarel]

Perfect timing, I recently drug home a free snapper LT1533 and I'm sure the Nikki carb needs work from sitting with crap fuel in it, got around to putting on a new solenoid (old one was melted, guy i got it from said the previous owner hooked the battery up backwards) and now need to see if the flywheel key is sheared as it backfires through the intake. I'd put on a Walbro if I had any left in my stash to be honest a bit simpler to rebuild. 👍

[@jonv8084]

Loved the info, awesome of you to explain it in easy to understand terminology.

[@edwarddinardo2830]

Just took mine about and cleaned it, no more flooding or surging, I will be buying a spare rebuild kit to have. Mine is a 11.5 B&S on a DR bush hog. Never knew the choke sleeve/plate came out that easy and spring was way to loose. Thanks

[@gordonjackson9243]

Awesome video, thanks, I just cleaned a Nikki twice, and I wish I watched this video before I cleaned the carburetor on my 21hp craftsman.

[@nashguy207]

Good Job buddy. This help a lot of us if and when we need to rebuild that carb. My shop all they want to do is to put new parts on including carbs they don't want to fix anything anymore. Have a great week!!!

[@doublewide6]

Well, at the price of new carbs it may be cheaper and it you go aftermarket it is guaranteed cheaper.

[@nashguy207]

@@doublewide6 I would agree if they where using after market carbs but they are using oem carbs and they pricey most of the time over 100.00 and then north of a 100 to 150 to take the old off and the new on

Thank you very much for the video. Good stuff. Lol I just came here to see which way up for float needle to go haha cause fell out and didn’t want to get wrong

[@bretlambky]

If you put the carb in a ziplock bag. And then fill the bag with carb cleaner. You can put it in the ultrasonic cleaner without making the water gross. You won’t need to change it as often either.

[@THEMOWERMEDIC1]

Now there's an idea. May try that in an upcoming video. Care if I give you a shout out?

[@bretlambky]

I saw that idea in another video, I wish I could remember who it was... lol Just reference you saw it on a fellow Tube junkie...lol

[@brucemullis479]

You saved me on this. I was not running the gasket to the outside of the perimeter of the plastic in bowl. Thanks

[@hpelisr]

Great job and explanation of how to service that type of carburetor. Those carbs look to be kind of simple, but if you understand how to work on them, they can be hard.

[@brandonstutts90]

Thanks for the video. It was a big help. I pulled it apart and dropped the main jet and didn’t see where it came from just like you said. Something tells me you’ve ran in to that problem before.

[@gingervytis]

Me too. Got my Nikki in pieces while watching this excellent video. Now I see where that jet goes.

[@joesphbaumgardner4579]

@THEMOWERMEDIC1- First time with this carb. The bowl gasket is a pain in the ass But Unlike most glad to see you talked about how that goes on. What I find more a pain is the little O ring that goes over the plastic nub where the main gas comes in. Some of these kits the ring is thicker or wider and it is almost a done deal to get all locked down. Same with the little O ring that goes on brass and up in center of plastic shoot/tube. Two things here #1. What kit and link do you get yours. I see they work well in going in and locking. I need some? #2. The thing at vid point 11:47 what exactly does that part do when ajust to carb? Puts more fuel into carb thus slows or runs motor faster?

[@thomasfiore7456]

just watched this video and it helped me with my problem, now back out to the shop to try it out

[@kevinhubbard8039]

great vid thanks

[@tihspidtherekciltilc5469]

I bought the rear engine Troy Built for $50 with a blown Briggs for parts. I went to clean the carb for a spare and there's no needle valve but at least the carb was spotless inside. Judging from the bowl screws I think this was delivered this way and why the engine seized. Great video BTW

[@dennislarimore9409]

Great Job!! I think I can handle it now. Thanks .

Nice video thank you. I have the same basic single cylinder briggs that had a walbro which the needle and seat failed. Do they have after market kits for walbro? I bought a new carb (Chinese) and it must need a larger jet.

At 5:33, what you called the "main jet" does it go back in with the little end first (on the side you used the pin to push it out).?

[@guypersico9106]

great job

[@victoryfirst2878]

Does the fuel float with new needle installed lay parallel with the carburetor body base when looking at the assembly from the side ??? Or does the fuel float just about stop at the top of the carburetor base ??? Thanks. VF

[@rickcruz1268]

Great video.. I am skeptical about how that gasket is designed it don't look like it would seal tight. I'm hoping it will work ok since I'm getting a kit this week. Thx Rick

[@doublewide6]

I find the plastic float tends to sag sometimes and that is why they flood. I would think the plastic seat would be fine if cleaned well with a q-tip. Have you ever tried to change just the float or heat it so the need sits correctly?

[@THEMOWERMEDIC1]

They sag due to the spring inside the needle. It's the way it's designed, just like the old toro 22040 Suzuki 2 stroke. The oring on the backside of the fuel transfer assy is vital in its placement as it is also a leak point

[@glennyj65]

Constantly!! After having my own shop for 12 years, I can tell you that I hate Nikki carburetors. They're plastic shit that needs to much attention. (good video though!)

[@ben-me9jy]

I had a Nikki Sixx on a Polan 38 inch 15.5 replaced everything on the interior and runs now I just couldn’t figure out how to get the adjustment on the carb but now I know thanks man

[@jclements007]

I bought a Nikki carb rebuild kit and the mower still didn't run. So I replaced it with a new carb for under $20 and it works.

I should use my ultra sonic more but I like to clean carbs even after all these years. Thanks Jeremy -----like

[@doublewide6]

I don't like the fact the USC. takes time to clean and then needs to be blown out to get all the water out. But no doubt the USC works great on old stale carbs.

[@BrucesShop]

@@doublewide6 I do rinse them with methyl hydrate (denatured alcohol??) when they come out to help with the water but it is still a time consuming thing. You are right.

[@BrucesShop]

@@kenhilson786 Same thing. Clear them out. Good for you.

[@butler386]

Hmmm I think I like the old carbs better. Not sure I care for the plastic so much. But maybe it doesn't corrode as much with the crappy gas we are forced to use. Great job

[@josephpuchel6497]

Hey great job. I see there’s different part numbers on those fuel transfer tubes but all look the same for 13-20 horsepower Briggs engines. Even the prices vary.

[@ezrafarmer3981]

Is WD40 the oil you used to get the gasket and O ring on? Trying to get an old nikki carburetor to work on a lawn tractor that won't start, to work. Do you think cleaning it and rebuilding it will make it work? The engine turns over but won't start. Thanks for the video, very informative

[@somerandomguy3868]

In the video he's using the wrong screwdriver. Nikki is made in Japan, do they use JIS screws. Choose to Phillips, but just different enough to cause slippage and cam-out of the screw head.

Hey Jeremy, do you know anything about the low end brass jets that I cant find anywhere except for that other guy on youtube who drills his out a bit. Thanks for the upload

[@450kman]

Thanks. The main jet snaps into place in both the inside and outside of the fuel transfer assembly but it only works in one spot. :) The online parts diagrams were no help, as they all had poor graphics making it impossible to see the proper location of the main jet.

Do these Nikki carbs use the same main jet ? For example is the jet the same on carbs off a 16.5hp and a 21?

[@glennyj65]

NO! They use at least a couple which are very different port sizes. Running a shop I picked up a bunch of Nikki jets from another shop, thinking they were all the same. I usually learn things the hard way.

[@billg4630]

[@josevasquez8193]

I noticed one linkage had an added thin fine wire and could not see where it connected. Can you please comment on where these linkages are connected to the Nikki ? Thanks !

[@ronalddavidwhite9385]

The "Governor rod" has a long thin wire like spring which accompanies it, They connect to the throttle valve (the metal one located closer to the front of your mower.... the valve nearer the back of the engine is strictly choke related and your choke linkage is attached to plastic. ... it has 3 holes, make sure the choke valve is in the open and hook the linkage up through the hole nearest the rear of the engine, oddly you hook the linkage upward through the hole not down through the hole.. Make sure to install the thick choke linkage through the slot in the bracket that your throttle cable connects to as you put the carb onto the air horn, otherwise you will not be able to hook the hook in the choke linkage on the carburetor. As for the Governor linkage with the very thin wire spring the rod goes in the hole that is lined with plastic in the spring goes in the hole that is just a hole in the metal linkage on the carburetor hopefully that helps!

[@cyberdude721]

would be nice if you added the sources for the parts needed OEM rebuild kit is near 70 bucks without the fuel transfer plate, I see you have an amazon site but didnt find parts for the Nikki any help would be awesome
