THANK YOU SO MUCH!!!! I was taking the carb apart and, yeah, this little thing falls out--don't know where it came from. Shop is closed for the holiday, manual just shows the parts but main jet is not shown connected to ANYTHING, and first youtube video doesn't say anything about it either. Carb is all torn apart and I need answers. THANK YOU SO MUCH FOR THIS VIDEO!!!
Can't believe 11 idiots disliked this video...hopefully technology advances in the future where you get shocked if you hit the dislike button for no reason other than troll.
Thank you so much😅!!! After first winter new John Deere d130 would not stay running. Figured gelled gas in carb. Took it off & cleaned it. I do remember now finding jet and not knowing where it came from. I was sure it belonged on that plastic tube seemed to fit great. Well , after, engine stayed running but has surged horribly ever since except levels off under load of mower deck. I have taken carb off a good 10 times or more googling and racking my brains for months with no success. I had been installing jet on top of tube instead of turning it over and pushing it up the tube to seat. I am certain that your video has solved a 2 year elusive problem for me. I can't thank you enough.
You should get an award for video helping the most people per view! My jet fell out and I found another wrong place to put it that no one else has found. Almost gave up until finding your video! Thanks!
It took me six times taking the carb on and off before I discovered another website that showed where the main jet goes. Runs like crap without the jet. Thanks for helping people.
You are a life saver, took apart my carb 3 times trying to figure out what I did wrong cause the main jet fell out and I did not see EXACTLY where it came from. Thank You....
First time I have dis-assembled a Nikki carb and some of the parts including the main jet had already come loose from their positions. After cleaning the carb three times, including steam cleaning , I had the cleanest Nikki carb in Scotland but it was still not working! My conclusion was that I was assembling the unit incorrectly. Your video confirmed my error and sorted out the problem; I had been inserting the main jet at the top of the mounting as opposed to placing it into the flow tube at the bottom. Garden tractor now working fine with it's B&S 13.5hp OHV engine. Many thanks.
I had figured it out by the time I saw this video but it's nice to get confirmation. The tricky part was that the o-ring was worn so it didn't stay in there at all. Thanks!
I can't Thank you enough that happened to me a few day ago. I put back together in the wrong place and of course it didn't start. Looking through my phone for something completely different and this popped up. I couldn't believe it, went out Took it apart put it back right and the tractor fired right up. Once again THANK YOU.......
You're the man. Rebuilding my carb now and I had to stop because of the damn jet. No schematic I found showed where it went. Stumbled on this while not getting an answer in another video. Thanks.
Had that problem today...spent a hour trying to figure it out... Glad you posted your video ....i just wish I had. Found it before I wasted a hour researching that jet.
you were a life saver with this video. I took my carb apart again and put the jet inside the tube oring side down. Prior to that I put it on top of the tube. The tractor now starts and runs great. Thanks
My first attempt at cleaning a NIKKI carb on a 10hp B&S engine, thought it was plugged up so blew out bottom of transfer tube and jet went someplace in the shop back wall, never to be seen again. $10 later all fixed. Lesson learned. Good informative video, wish I had seen it before I got out the air hose on mine.
Thanks Rob for taking the time and energy to post this video. I did not think that I would find this information but here it is and you did a great job answering it. I cleaned the carb and thought that I could get away without replacing the bowl gasket. It leaked right away. The second time I removed the bowl the main jet dropped out. I lost track of how the main jet was oriented (I knew where it went ok). Again thanks, you are awesome.
You're very welcome. They don't run too well if that jet is in the wrong location. If it falls out easily, its usually an indication that the o-ring is worn out. Unfortunately, the o-ring is not serviced, but a new jet comes with it. And it's cheap.
Thank you for the video. Best two minutes of my day today. I'm working on a B&S with a NIKKI carb, and the jet dropped out on the workbench. I thought, "Where did that come from, and where the heck does it go??"
Rob I want to thank you so very much, I searched for this information for about three days and finally found yours. Im currently in Puerto Rico after Hurricane Maria struck and every one here is depending on generators. some one took apart my friends carb and apparently didn't put the parts back in the correct order, this video is a life saver. Thank you thank you
Thank you so nmuch!!!! I'm in Brandon Florida. Hurricane irma is berring down on us. My generator with nikki carb was acting up. I put in a new carb kit and could not get it to run good at all. As it turns out after comming accross your vido, I had the main jet under the fule float neddle. WRONG PLACE... Just in time for power outage!!! THANKS YOU SAVED US
Best video online. Thank you so much, I had actually put it back together, but the gasket was broke during re-assembly and the carb flooded. Thought I put the jet in the wrong spot, until I saw that gasket was split. Thanks
Fantastic, found jet but was not going to guess where it went, googled and pulled up this and it makes it real claim. have other carb in past that had it in same tunnel way but always screwed in, really supersized me. Thank you great answer. I am working on 22 hp lawnman, breakout shows main jet standard and high altitude but not where it goes. Thank again
Great video. I was cleaning my carb for the first time & accidently blew the main jet out with compressed air. Couldn't find anything in the assembly drawings to show its location so thanks.
Wow. I knew where it went, but had put it in upside down. Was about to order complete carb. Lifesaver - short, and to the point with the title. Thank You!!
Thanks for the timeless video. After an hour of attempting to find the main jet location (and several hours of searching online) I had settled on the location shown in your video, but probably had not pushed it down sufficiently to get enough clearance for re-assembly. I will push harder. thanks again, a grreat help.
Usually that o-ring is worn out and doesn't hold the jet in. You have to buy the jet to get the or-ring. Unfortunately, you can't get the o-ring separate. Glad you got it back together.
@@302vettelife2 do you think if the o-ring is worn out the jet won't work right? Mine doesn't stay in either but I assume it gets pushed into place upon reassembly?
@@pogtuber5146 I honestly don't know. The fact that most of these jets fall out easily, leads me to believe most of the o-rings are worn out. I haven't had an issue with how the engine runs though. BTW, I was unable to replace that oring. You have to purchase a new jet to get the whole deal.
@@302vettelife2 thanks, I'm looking at a rebuilt kit. The big circular gasket that seals the passages and float bowl seems to have stretched over the years as well and doesn't appear to fit correctly either.
@@pogtuber5146 Yes, they are super common to deform. Also a pain to put back together without pinching that large seal. The Nikki Carb was a terrible design for small engines. Good luck with it.
Thanks pal, no F-ing shit! Where did that little jet come from? As soon as it fell out I stopped what I was doing and checked RUclips (God of Instruction). Really appreciate you taking the time to post this. I'm doing repairs during a snowstorm!
Rob just like to tell you that you saved my ass I could not figure out where that little jet lived I spent several hours on youtube and removed and installed the carburetor so many times I thought I was going have to replace the carburetor just to find out where that jet went , again thanks.
You are a lifesaver!!!!!!!!!!!!!!!!!!!! this damn mower finally mowed my grass after a month of BS... I also upgraded the needle to brass... those plastic ones stink ....thanks again!!!
Thank you for this information, I was one of those people who thought I knew where it went, ran like shit, so I was wrong. You enlightened me and I fixed my error, and now she's purring like a kitten
Thank you! I've had a lot of troubles with the carb recently, and after installing a new carb kit and cleaning the other parts I was still having issues. Turns out I had reinstalled the main jet upside-down, and what's more neither the new nor the old jet would fit into the new housing, so I had to use the old housing with the old jet, with of course the new needle valve.
Thank You!!! I've got Hurricane Harvey about to hit, my generator won't start I pull the carb and then... wait what is this little deal and where does it go? Your video was my Savior today.
Huh.. I thought I knew where that jet went until I watched your video! Don't know it it made a difference, but I put it on the metal stem first. Thanks!
Thanks. I struggled with this today. The parts diagram does not show the jet. I tried all those locations and more. Took off the carb and put the jet in. Presto my engine was running.
Thanks a bunch. I have been taking this carb apart and putting it back together for 2 days. I watched this and right away I knew what I had done wrong. You are my hero. The other thing I had been fighting was the little spring on the top. I must of spent 2 hours or more on it until I got lucky and screwed up and got it right. Do a video on the correct way to install the little spring that controls a butterfly. Thanks again.
It's bad design that the main jet perfectly fits in so many places. Mine fell right out as the carb looked basically brand new inside, yet the engine wasn't starting. I cleaned a very small amount of crud out and it runs like top now.
God bless you Sir! I have been jacking with this and the mower shop even told me the incorrect installation. I knew it went in the way you show it. It's truly a miracle. Thank you youtube too btw.....lol
The O ring on the jet is likely worn out. At some point, order a new jet online. They're cheap. The jet comes with a new O ring. Glad I could help you out.
I couldn't find anything online either so I had to call the factory asking if they have any explanation were the jet went? I ask them for an exploded view of the carburetor they had none so I had to figure out myself. After 4 reinstalls and removals I got it right. Poor design and poor customer service resulting in a waste of time. Wish I had seen ur video first.

Thank you!! I rebuilt my Nikki carb like 6 times because I put the jet in the wrong way, so it ran too rich.
Glad I could help
Had the very same thing to happen. Watched a couple of videos in this carb. Glad I came across this ine addresses that particular part.
Just happened to me a few min ago, you got my attention, I opened carb carefully and jet popped out like spring loaded.
I had figured it out by the time I saw this video but it's nice to get confirmation. The tricky part was that the o-ring was worn so it didn't stay in there at all. Thanks!

You sir are a legend, this has saved the day
just what I been searching for hours life saver
Main jet...took me a hour watching RUclips to figure out where it went.
Thanks a million!!! Thats exactly what happened to me!!! Excellent video to the point!!!!
Thanks for the comment. Glad you got it going!
Like many others have said a very useful video, exactly the help I needed....thank you so much.

I echo the comments of others-- THANK YOU
Put me in Beverley Mitchell's column you saved me thank you so much
Hey Sir thank you so very much for this information on the valve. You are detailed.
Awesome saved me a lot of frustration !!!!!!!
Agreed bev.ty very much.this is first video i have found to show where that jet goes.
Thank you for sharing this ..
