Nikki carburetor man jet O-ring

[kebo]

This dude is next level repair tech! Thank you sir!

I fought a surging carb for months and couldn’t figure out what was going on. Watched this video, installed that o-ring, and my mower runs better than it has since I bought it! Great video!

Adding that o-ring on top of the jet immediately fixed my surging problem. It was so bad I had to park the mower till fixed. Replacing the o-ring on the jet itself did not fix it. You could see where the metal tube and the jet mating surfaces polished each other from the jet moving in the cylinder.
This problem has periodically shown up and disappeared without explanation.
Thanks so much for an absolute solution to the problem!

The main jet on my nikki carb had no o-ring. I re-installed it without and placed the Harbor Freight o-ring size( A006 ) you mention in No BS ! between the emulsion tube and the main jet as instructed. There's a tiny bit of resistance installing the bowl (as if the o-ring is a tiny bit too thick) and the waffle gasket is barely contacted when everything is fitted properly. Will tightening the bowl screws squeeze the gasket sufficiently ? I would prefer to use the o-ring that goes ON the main jet, but as you state, I don't know the size, and don't want to order the whole kit just for 1 o-ring. Thank you for the vid !

Many thanks. Have a mower with a Intek 7-160 V-twin suddenly started surging. New plugs, new fuel filter, fresh fuel still surging. Pulled out the carb took off the float chamber and as I lifted up the white plastic cover the main Jet fell out. Tomorrow, new o-ring and hopefully the surging will become a thing of the past. 🙏🏻

I have been trying to fix several Nikki's with this problem in the shop I work in. Fairly new Johnson lawn mower with the Nikki carb.
They flood over and everything seems fine.
Carb kit don't work. I'll see if this trick will change the outcome. Thanks for the tip and the upload, Subscribed and thumbs up!

Fair play brilliant video manage to fix my dads ride on with this method his main jet o ring was floating not seating properly so I fitted the small o ring on top and hey presto she runs again! Thanks mate!!!!

Thank you so much sir! The carb on my Briggs platinum engine messed up, it acted like it was starving for fuel, when I cleaned it up and put it back together, it had the opposite problem, it flooded out, so I watched another video and your video and discovered the role the o rings can play, so I’m taking it back apart and I’m going to make sure the jet is in there an place The o rings where you and the other video showed you must have them . This after I bought an expensive Briggs rebuild kit that didn’t have all the parts you might need.

[baggins]

THANK YOU Bro! What an obvi tip I had completely not even considered

[chadfield]

Good idea! Going to give this a try the next time I have my Nikki carb apart:-)

[walleyeye]

I did this today just to keep the jet in place and it works awesome!!!

[zesthraxGaming]

Your the man! Great solution you’ve concocted!

[ludvigjakobsson]

Thanks for a nice video, Do you have any experience with a sticky needle? It feels like the carburetor will not be filled wit gas fast enough.

VERY INTERESTING A CARB I`M GONNA TRY THIS ON TOMORROW

[Hondame]

Great Video! question: my Nikki carburetor is a model 698945, I need to replace the small o ring and the base gasket you mention as it keeps flooding but can't seem to find one for my model Carburetor, will later model ones do the job, any info would be greatly appreciated.

Will those harbor freight viton orings work on the other jet

[chucksmoko]

Just wondering if anyone who has done this if the harbor freight kit o-ring is the same size as the original main jet o-ring or is is different size?

Said differently, if ya had a good new o-ring where it’s supposed to be per OEM, would the second one even be needed? Some Nikki kits don’t come with the jet o-ring …. some do.

My 17 1/2 horse Briggs & Stratton start surging out of nowhere checked everything even replaced the carburetor still surging is it possible O-ring is bad on the new carburetor what's your thoughts thanks
