Yup I blew out the main jet apparently that’s why it was ramping up & down starving for gas . Great job thank you . Jerry

This guy is 100% CORRECT on this. Kudos!!!!

[ueww]

Thank you so much for this video. This is exactly what happened to me. When I removed the bowl and the plastic part the main jet fell out. Fortunately I caught it and did not lose it. But when I put everything back together I had no clue where the jet has to go. I finally figured it must go between the solenoid plunger and the plastic part. When I tried to put the bowl back naturally it no longer would fit. The solenoid plunger touched the top of the jet and it drove me crazy for 2 days. Thanks to your video it showed me that the jet goes inside the plastic part and not on top of it. Great, great video!

Boy thanks buddy I watched your first video and I still put the jet in the wrong place thank God I came back before I tried to start her up

I spent a while, looking on the internet to see where that tiny brass jet belonged. Most things are pretty intuitive, figuring out where they're supposed to fit. This one had me stumped for a while. Then I wondered if it was supposed to fit down in the stem of the plastic float assembly, as it was tapered, and o ring side in 1st. I gently pushed it down in with a jewelers screwdriver and it felt like it seated. As I still wasn't certain, I kept looking, using different search terms, till I found your video. Thanks. I already cleaned up the carb. All that's left is to test the fuel solenoid before putting everything back together. The other trick is to hold the plastic float assembly on the bottom, and set the rest on top so that tiny jet doesn't fall out again. Great video!

Thank you for taking time to post this video!

Thank you Baldeagle, excellent presentation, that explained a lot.

[Rein_Ciarfella]

Thanks, Steve! I haven’t come across one of those yet, but I’ll certainly be looking out for it. I learned from Bruce to disassemble and reassemble carbs in a baking pan to contain errant parts, so I don’t expect to lose that jet, but knowing ahead of time which way it goes in certainly helps. 🔧👍

Love your vids been a subscriber for a couple years 😂😢🎉

[williamritze]

Thank you, I was not certain which end the fuel jet should go in the float bowel. I had put it back in correctly but did not want to put everything back without together without being certain to the correct way. By the way, the leaking fuel is no more and the engine fired up on the second pull.

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 vids !

[austinsmith]

Thankyou been flooding my oil with gas and having hell fixing it!

[kdcarver]

Thanks for these tips. Do you happen to know what the screw specs are? The Phillips heads on mine are easily stripped (they must tighten these with a gorilla) when removing, and I'd like to replace them with a hex or torx head bolt.

Hey Bald eagle... I've had quite a few of these nikki carbs where the tiny O-ring had deteriated ..they leaked fuel into the crank case..causing bad problems.. it's not a bad carb i know a lot of small engine machanics that hate them..i always tell them at least it can be repaired.. it's the fuel that attacks the O-ring..i use non ethanol fuel in all of my equipment no problems after 3 years..
Nice picture of your grandad you got hanging on the wall..lol.. Cheers 🍻🍻🍻🇺🇸🇺🇸🇺🇸

[goirish]

Quick question. Just rebuilt the Nikki carb on my craftsman lawn mower watching your video. Worked great and solved my leaking gas into oil problem. I changed oil and filter too. Mower runs great on run but backfires and hunts at low idle. What do I need to do? Screw adjustments? I put them where they were. But I’m not sure how much to mess with them and I assume it’s the low idle jet screw? Any help
Would be appreciated. At least I’m back mowing

[gregthomas]

Yup. My main jet fell out and I didn't even know it. Fortunately the new kit had a replacement. A little bit of ignorance goes a long way. We'll see how she runs now.

[devinjonathan]

The whole in the middle of the jet looks smaller on the new ones from the kit then the hole in the original nikki carb, will that be a problem? Im doing a rebuild now and the oem jet has a bigger hole

Noce tutorial on the nikki carburetor steve 🔧

[betavirus]

the tiny o-ring in the middle needs to be seated all the way down or you'll have that space.

[tombley]

It's an expensive repair if you need to buy a kit for 2 o-rings.
