AFTERMARKET CRAP! Swap Over A Nikki Carb To A Walbro Aftermarket Carb On A Briggs Engine

[@nickg421]

OMG Thank you! I have been struggling with my Nikki carb for months. Rebuilt, generic replacement, put a manual choke on it, and I couldn't get it to stop surging. Bought a $15 set of jet drill bits on amazon and now it runs perfect! Thanks Teryl!

[@TarylFixesAll]

For those of you that didn't pay close attention to the video, you can clearly see the shafts are completely different. The choke and throttle shaft linkages hook up differently on the aftermarket carb (which you can clearly see in the video). That is because the aftermarket carbatrator is for a different engine. After a lengthy search a direct Walbro replacement carb was found. There’s a link to it in the description. You can still use this video as a way to troubleshoot how to make a carb work that isn’t the right one. Now There’s Yur Dinner!!

[@fair2middlin]

After slowing the video down, I can see that the shaft top plates, at least the throttles, point different directions. I am very glad you did the video because my Cub has the Nikki carbatrator.

[@jeffreydolph6469]

I was wondering if you have experienced the problems with the new ariens carburetor s. They constantly surge, mine has since day one. I think it is the side jet that has tiny port in it for EPA bs. If you have any fixes or info I would greatly appreciate it .

[@donireland2640]

This was a hoot. I learned more in 3 minutes than i gleaned in 3 days of researching my carb problems. I've got a $2000 mower with 37 hours on it running a nikki. (Surges) Back to square one.

[@whizzo55]

Watched this yesterday, went to HF and got some drill bits today and now my 15.5 hp Briggs is sounding great. Thanks a million!

[@burtburt1755]

Did you replace the Nikki with a Walbro?

[@obfuscated3090]

Trick to accurately sizing bits is to use the smooth shank as a gauge. I drill jets by gripping the shank in visegrips then spinning the jet between thumb and forefinger, then after the bit breaks through slide the jet up and down a couple of times to deburr the hole. I've done this with motorcycle carb low speed jets since the 1980s and just now got into Briggs because I want more power from my mower. If you mix up your jet drills use a micrometer or the very handy Harbor Freight digital calipers. (They're accurate too, and let me leave my expensive Tesa and Mitutoyo in the machine shop.) Excellent video!

[@ronkpaws1]

I had to fix a 1980's Craftsman edger with a Tecumseh 3hp engine with a diaphragm pump type carb that is unavailable in most places or to expensive to buy. I replaced it with a bowl type carb with the same choke and throttle plate set up as the old one. It was for a newer Tecumseh 3hp to 5hp engine and it worked great. Matching it up with the pictures on the innerscreen was the hard part. Thanks Taryl, good video.

I bought one of those POS , said it was for a 14-17 hp I was working on a Briggs 15.5. it ran almost as good as the first time you put the carb. back on. I kind of thought that it would have to be drilled out. But I do not have bits that small. Now I see you had to drill out for the butterflies. Kind of glad now I rebuilt the old one. I got 13.5 I will try this on. One mower I had came with the Nikki carb. it gave me Nothing but trouble. Had it cleaned and rebuilt. But it never ran right. As luck would have it I got an old blown engine with a Walbro carb. on it. So I rebuilt it and put it on and it worked.

[@rverro8478]

Start playing with the choke. It will be a good indication if it runs too lean. Make sure your gas is fresh.

[@darenyoung8045]

tried this with same mower but has a 19.5 briggs and the the main jet was already bigger than a #62 drill bit so jus changed out the shafts installed it and it does GREAT!!,,,,,no popping surging...etc..etc...

You can use a fine saw to lengthen the slot and sand the choke shaft to fit without drilling. Just done that to my nephews push mower and it worked well. It'll work in a pinch to get him back to cuttin.

I would like to change it over to some type of Walbro carb. I have done the vertical shafts on my other mowers and they are great now. However I don't know what to put on this engine.

So much easier when you could adjust the main jet screw especially if you going to cut deep grass and you need to make it just a bit richer to keep it running smooth and cool the cylinders and prevent detonation or valve burring and all that.

[@TractorMonkeywithJL]

Lol. I agree with the expiration dates on consumables, but when I worked for the Air Force they would take it away the second it went out of date regardless. Trouble is, stuff would almost be out of date by the time you got it in from supply so you would be lucky to use it for a couple of months. Just like tools that need calibrating. It's good today but at one second after midnight, forget about it or get wrote up. hehe.

Well I bought 3 of them NIKKI carbs and they are nothing but JUNK!! Feeding them Loctite will not help anything. New out of the box I am getting a bout 1 day of run time, however the last one didn't last 30 minutes. The worst part is I threw the old carbs in the scrap and hauled them across the scales before knowing the problems that was coming!! I saw where the Key Board cowboys said they interchange, but I figured they didn't know a hard drive from a paper trail!! So I am glad Taryl did this Video. I have ordered two of these carbs and gonna do the swap. I have the same exact tractor that he was doing in the video. Anyway I am tired of the junk!! Thanks Taryl

[@robertoruiz7069]

Hi taryl,you could try to buy a metric REAMER for 10.00 buck at mcmaster and ream the holes .measure your shaft with your dial calipers to get the exact size of the shaft.reamer come in straight cut and spiral {that's for holes that arn't solid all the way through.reamers come in sizes by .001. example 1/4 in = .250 ...so you can get .248 or 249 or oversize at 251 or 252 ect. you'll have less air leaking with the right fit. great vids.

[@anthonyhugger5447]

Hey there! I love your videos, not all day are you hilarious, but I’ve learned so much. I have a 19 horse Briggs & Stratton. I have a Nikki carburetor that was on there and it wasn’t running very well, so I bought another Dickey carburetor and it runs good, but it still has a little pop. I have adjusted the valves nothing better. I did buy a Walbro carburetor from Briggs & Stratton to swap it out because I’ve been told that that is the fix. What I don’t understand is the high speed adjustment. I think you could run much smoother like the one in this video but I just can’t seem to get it there any advice? Thanks!

[@autobotavengerfireballxl5339]

So if it runs rough while its choked its not getting enough fuel?

[@springfield4522]

I think just the opposite - it was rough when not choked, he pushed it in, slowly closing the choke, which restricted the amount of air and enriched the mixture and then it was running better.

[@autobotavengerfireballxl5339]

@@springfield4522I totally agree with you thats why I question it. I think taryl just misspoke

[@dwaynecallow8152]

No it runs rough while it is not choked ,by applying the choke it lessens the air flow resulting in the motor to suck more fuel in which creates better fuel/air ratio. If all is good it should run rough with choke on or stall out due to not enough air for good combustion ,the choke is to help in first /cold start to get fuel flowing plus more fuel helps boost combustion til it warms up n parts expand to operating temperature

[@chadr00]

If the engine is surging without load why would you not increase the low speed jet diameter? I was just working on one of those Nikki carburetors on a 13.5 horsepower and the throttle butterfly is nearly completely closed at idle so the main jet would have no effect even at higher speed without load on my engine. I increase the size of the hole for the low speed jet and then I was able to use the adjustment idle screw and give enough gas to stop the surging. I did not touch the main jet yet. I'll have to see how the mower dies under load.

[@chaloner1234567]

Excellent videos!!! Love they flywheel trick!! What’s your opinion on adding washout ports to a rear discharge ride on? Do they really destroy the spindle bearings? (I have to cut wet grass anyway)

[@mrbrown6421]

To: paul chaloner I seriously doubt a washout port affects the bearings...however... My 'boss' is a MASTER at hitting every tree stump, tomb stone, concrete chunk and buried alien spacecraft with 3 miles. Now THAT guy easily destroys spindles, bearings, guide wheels, blades, tires and my PATIENCE. Painful to watch. I built a ramp to run the mower up on, and wash it off with a garden hose. MUCH more efficient. Washout ports seem to leave 20 percent of the gunk under that deck. Run blade off the ramp to dry it out. For my push mower, I embedded a PVC pipe flush with the ground pointing straight up with a PVC cap that is drilled out to shoot a geyser out of it. Hours of fun for the dogs. Just push the running mower over till clean. You can't see the PVC till the water is turned on, so I wait till someone walks near it, and reach over to the valve behind me, and turn it on for some fancy dancing! Good luck. -- North Central Florida

Bought a cheap Amazon replacement carb to salvage a Sears/Briggs generator that had been submerged in flood water and sat for a year. Original carb was toast, but engine still rotated. Replacement carb ran too rich, but let me test engine for an hour to make sure it wasn't going to blow up before I spent more money on it. Bought correct OEM carb for $100 and it ran perfect. Generic carbs are okay, but aren't an exact match. I had a time constraint, Harvey was coming, so I shelled out for the OEM part. Otherwise, I would have experimented with drilling out air passages to bleed in more air. It's a generator, not the space shuttle, and only needs to run good at one RPM.
