Yamaha Outboard Carburetor Cleaning | Yamaha 90 Carburetor Rebuild | Boats.net

[@pederlindstrom3132]

Greetings from northen Sweden and a fellow mechanic. Video reminds me of a guy in the shop that did what you did now, only it was 4 carburators. He took it apart and mounted it back on the engine, walked back in the shop to get the key and right there on the bench is one jet and a float... Need I tell you it was a friday afternoon.

[@E-mobilizeEbikeRepair]

Found this right after doing it on my own... Oh well turned out great! Super informative video ! very helpful ! I did a rebuild on a 50 hp Yamaha 2 stroke 2003 and the carbs look identical.

[@gregwesthoff6206]

Excellent demonstration in breaking down the carbonators .

[@KeepatIT69]

Awesome job! Very detailed and thorough. Thanks

[@colewitherspoon2922]

Clearly explained, excellent video quality! A joy to watch about a task I dread. Thank you!

[@stephenboyce9841]

I agree with the comments about checking the float height. Great video but you should not have to press down on the float tang to fit the needle and if someone follows this procedure on older carbs with adjustable float height - then their fuelling will be out across the rev range. You also should balance the carbs against the master carb after cleaning.

[@Adeesicks]

Balance the carbs against master carb?

[@RayJones-u3t]

Awesome job bro

[@yunierperez8987]

I just did mine today it was easy thanks for the video

[@bftcoman]

Is there any carb tuning after??

[@satyendrarajput5045]

Really liked it ..very nicely explained!

[@bftcoman]

Should you replace all the fuel lines to avoid future failure?

[@Jcberry89]

Do you ever install the other larger Oring?

[@BayouBoyz36]

It goes on the bolt that screws into the side of the float bowl

[@emccallum1012]

Great video, thank you for sharing. I will add that a good set of JIS screwdrivers are the proper screwdrivers for Japanese screws. Their phillips and ours are a different shape.

[@TheRealKlinky]

What the about link & sync procedure 🤔

[@chadkochmann7958]

Great Video professional well done.

[@vincesmith5846]

Excellent made video!

[@AchikSarih]

Merci beaucoup ❤❤❤❤❤❤❤

[@michaeldavis4793]

Very Instructive Video. Thanks

[@dukemanvillle]

Great Video.... Do you same the same video for a 2008 Yamaha 50tlr rebuild ?

[@tilendynaguy4895]

Job done 👍 🤨 But does it fire right up and ride out

[@ppanditharatne]

GREAT PRESENTATION

[@gregoryfortner6038]

It would be nice to hear it running after cleaning the carbs. That way I would know how it is supposed to sound.

[@connerocks]

Supposed to sound like “bwop bwop bwop bwop bwop bwop bwop”

[@toupsclassroomtoupsclassro9557]

50hp yam 2 stroke......is the float parallel to carb body upsidedown?

[@cjharrin]

Great video! Question - Is the process much different on a 1999 4 stroke Yamaha 100HP TXRX?

[@schreck425]

Fantastic video, unfortunately it skipped the part about how to hook up properly the oil linkage... and then said it will cause engine failure if not done... Mine won't go on properly so now I'm stuck on what is the correct way to hook it up.

[@nilob1]

This helped me alot, thx!

[@outboard_usk]

Hello from Russia!

[@jasonstafford1064]

What's the difference between the 75 and 90 hp models they both have the same carbs intake and power head listed is there a restrictor in the exahust or does the exhaust manifold restrict it

[@Monsterolla]

Different jets and timing

[@smokster0604]

Awesome thanks.....

[@kim8839]

I have a Yamaha 90 with carb problem "C90TLRZ". Carb is leaking out of one of the vent holes on top of carb while motor is running. I checked the 'needle and seat' which has no pits. Do you have any ideas of the problem? I'm thinking it maybe a heavy 'float' which maybe flooding the carb. Fuel is also leaking out of the passage of the throat of Carb.

[@kim8839]

I solved my problem, everyone said it was the needle/seat in the carburetor which it could have been. Ordered new needle/seat and float. Well it turned out the new float weighed in at 176 grains, old float weighed in at 425 grains. Changed the float only and problem solved.

[@keithclark2786]

Great video now can you tell me where can I find my pilot Jets and Main jets for my 90 Yamaha engine it seems that boat. Net does not carry them I believe only in a 45 and 65 they had where can I find a poor by 90 or are they all the same

[@yamahass66]

Is there any idle-screw? Or wich one does that? Anyone?

[@brucesilun9585]

You didn't show how or what the float level was supposed to be ( very important for any carb)

[@jtmcculloch]

These Floats are non-adjustable - Solid Plastic mount for needle

[@Foreverknight87]

Is this the same procedure for a 1988 Yamaha 90 ETLG? I also may need carb parts for this engine, so if anyone can point me in the right direction, thanks.

[@mr.aztec0664]

Once the set screen for the main jet was removed did you just take a pic to poke it out ? On my system top carb it falls out but on the bottom it seems to be stuck is there a way to poke it out without damaging anything?

[@taylorfurman6183]

You pointed out two small O rings one was smaller than the other but what was the thicker small O ring for?

[@GrimpleGromple]

The Thick O ring is for the Drain Plug thats on the carbs.

[@leerivenbark]

Thanks guys...I was just sitting here staring at that oring

[@dukemanvillle]

Nice video.. I have the 2008 Yamaha 50 TLR and I just rebuilt the carbs. I had to drill out the brass plugs to get to the pilot screws.. I replaced them with the new ones in the kit but my manual doesn't say what the setting would be for each carb. does anyone know how many turns I should back them out for each carb? Thanks !

[@ltbordo]

What were the old ones set at.

[@patonbike]

Would the process be similar for a 96 Yamaha Pro 50?

[@jcaprietta]

Are these carbs similar to the F90TLRB?

[@marcoaurelio9879]

good afternoon, please which initial adjustment of the carburettor air bolts, on yamaha 60 fed thanks

[@joshmiller1146]

Would this be same as a 2004 150TRLC?

[@brianmccarthy9860]

although he is a good tech, why did he not remove the top side of carb and check all the passage ways, idle mixture screw , and check float height, if ur not gonna do it all, let somebody else do it.

[@FloridaWild]

Why didn’t you replace the large gasket on the top half of the carburetor?

[@jimmymamales918]

I have a 1994 Yamaha 2 stroke 70hp engine I rebuilt all 3 carbs and replaced the cdi unit and spark plugs after that I took it out on a fresh water lake and at first it was hard to start, the engine idled fine but when I gave it the throttle it bogged down and shut off I restarted and gave it throttle again as I was taking off it bogged down again, i backed off the throttle then thrust the throttle back and forth until I finally got it past that point of speed but the engine could only push the boat to reach speeds up to 34 mph where before I could go 55 mph plus on my small whaler! It still boggs down everytime I take off? What could be the reason it is running rough like this and not smooth? Could I have possibly bought faulty plugs or do I have a fuel problem?

[@vanstuff1381]

Float heights set properly during rebuild?… just a suggestion 🤷‍♂️

[@mikko5639]

Looks like you didn’t get that floatseat off properly?? It looks damages. Is it have proper tool at all? I take my Dremel and cut little slice in the middle to get it off!

[@kevinbrown5977]

What is the purpose of the plug for the pilot jet?

[@martymcdaniel1950]

Without that plug the carburetors will flood soon as you crank them up.

[@miguelrivera6319]

I got a 90 horsepower 2005 start up very shut up after a minute

[@troytorman1131]

Are you the older brother from Little Sheldon?

[@zebclark9288]

Thank you

[@orrion76]

Bow to your master!

[@zebclark9288]

Jared Terman Deez Nuts!!!

[@tonyasadulin1296]

i have a motor like that after cleaning carbs it makes squeaking noise and cuts off on low idxle, check the video out its under Roman Nesen

[@vitaliivanov77]

Хорошее видео, но вы не бережёте руки, и нет очень важного момента - проверить что поплавки в горизонте. Разные ремкомплекты карбюраторов дают разные углы работы поплавков. Приходится подгонять шляпки игл - подбирать или подтачивать.

[@lukedawg357SIG]

Is Yamaha jets holes smaller than others I just paid a place to fix my 88 pro v and he said the high speed jets holes are very small.

[@martymcdaniel1950]

Yes

[@michaeldavis4793]

You can go with a slightly bigger jet. Mostly from a smaller hp Yamaha engine.

[@hp3453]

No float adjustment necessary?

[@jtmcculloch]

These Floats are non-adjustable - Solid Plastic mount for needle

[@georgeroney7503]

What would.cause the engine to just die after running for 10 or 15 minutes we let off the throttle to slow down the engine cuts off ,want start again you have to wait about an hour or so and it will fire up again , then the same thing happens

[@hooklinetinker9680]

That's not a vacuum line at 4:20 & 19:55, that's actually the fuel enrichment line that sends raw fuel behind the #2 reed valve assembly at startup. Great video otherwise. Very informative.

[@marioseguna7972]

No info abuot the other carb which have different use.

[@jamesglancey7980]

Where in the heck can I get a 10mm thin wall spent 55 dollars so far

[@tp2273]

I use a 10mm nut driver. Works great.

[@marcinmichalak1769]

Hi I have 1999 75 hp TLRX model with set of carbs the same like the 90 hp from video. I’m trying to buy carb kit according to parts manual from boats.net going by serial number and it shows completely different set of carbs. Do I have wrong set of carbs installed? Engine is original. Did Yamaha produced 75 hp with 2 different set of carbs for that year? Anyone has 1999 75 hp TLRX with set of carbs from 90hp? Thanks everyone

[@Monsterolla]

Same carb just the jets size are different and the timing also

[@martymcdaniel1950]

how come you didn't take the top of the carburetor off and see what kind of build up in trash was in it and said just taken out make sure screw there's trash all up in there 90% of the time

[@chiphill4856]

When he told us to start by removing the cowling...ugh

[@tyslink]

Just dump a can of Seafoam in the tank and call it a day....

[@blakelaperriere4586]

what about gloves...

[@michaelh7527]

To be honest, a lot of times gloves get in the way. It's a good suggestion though!
