***ABOUT THIS VIDEO:
I have had a few problems with my Suzuki Eiger 400 ATV not running great lately. I'm chasing issues and then one day I mentioned to a friend I was having trouble starting ATV when cold.
He told me to remove the carburetor and check the diaphragm. He said it could be stretched or ripped. Sure enough it was stretched and ripped.
I ordered a new carburetor diaphragm before I even removed the carb because I thought it was likely old and needed to be replaced. I'm glad I did.
If your ATV won't start or if your ATV doesn't run well, it's most likely the carburetor.
I bought this used 2004 Suzuki Eiger 400 in 2017 and it ran really well until January 2020. But I knew it couldn't run this smooth forever because lets face it, it's getting old and ATV parts wear out.
If you have a hard starting 4 wheeler I hope this video sheds light on your problem. It's one fix to think about.
I've also replaced the fuel petcock on this Suzuki Eiger, here is the video for that:

Thank you. My Eiger has been running bad for years and finally quit on me while snowplowing this year, leaving me in the middle of the road! A new carb was actually pretty cheap on Ebay and I switched it out with the help of your video. Afterwards she started right up and purred better than before the "great gas explosion" of 2017 (my last attempt at fixing it. Took my eyebrows a while to grow back). Thanks again!!
I don't have any knowledge of ATV's Roland, I watched your video to give you support my Friend!
Thank you Wendy!
Good demonstration, Roland. You obviously know what your doing.
Not really, I just make it look good. Haha
Well done Roland. I would not even know where to start!
Thank you Lorrie!
I always like seeing something to show the issue, so many times with carbs it seems you miss seeing whatever little bit got in the way...
Great days to you and yours !
Have a good Sunday Canadian Bubba!
It’s amazing how one small part can shut an entire piece of equipment down.
Pain in the rear that's what it is. Lol
Same thing just happened to my buddy clint he found it last night and fixed it, now it runs great
Great to hear Andy!
Great tutorial, Roland. Useful for lots of people, not to bad to do, either. You barely got your hands dirty, 😆 Great Job! God Bless! Take Care!
I know right, no dirty hands but smelly fuel on them. Haha thanks Angie
Goodmorning stopping by for a visit thanks for sharing very informative.
Thank you friend!😁
We had a hard time at our farm in the winter with our ATV's not starting..... If we did not use them every week.
However it was because the battery would die because of the cold....I would not be able to begin how to do what you just did...as a chef I don't like putting my hands into small spaces..lol
7:49 and you took out the spring and found that diaphram....I would not be able to put it back...lol
It is interesting to learn and watch you...
Thanks, I usually take pics while taking things apart so that I can reference to the pics if I forget how to put things back together. I did this once before so I remembered.
I hope you get the idle back down.
Good luck 🍀
Have a great day and be safe out there!
Thanks David, working on it today.
Interesting on how something so small can shutdown the whole ATV. Great job on fixing it all. 👍❤
Yes and it's a real pain to. We will see how it goes here on.
Hello from Tweed, Good video, have a Suzuki Vinson very similar bike, can't get my carb off with my giant hands without pulling the gas tank on mine, good for you for getting it in and out so easily. I had to replace the plastic nut on my choke as well. I ordered just the nut itself from the Suzuki Dealership in Belleville, and only paid $7 for the nut. If it goes bad again maybe try and just get the nut from the dealer. Good luck, take care.
Hey nice to meet you! Have you tried removing the air box to get the carb off?
Hopefully that takes care of it. Thanks for sharing Roland
Thank you Charlie!
Where did you buy the plunger on amazon do you have a link?
Yeah good video! We've got a similar issue with our Canam...really need to get it repaired. Good stuff 👍
Thank you!
Hello, I have a 2000 suzuki quadmaster 500( lta500f). It seems to me your eiger is the same machine as mine but after 2002 suzuki just changed the name.pretty much most of what i see on your eiger is the same as my quadmaster as fas as interchangeable parts...Am I accurate?...Your videos are of great help to me servicing my quadmaster, ty.
Pretty much in most cases
I hope this helps
Me too, thank you Sherry!
I just bought a 2004 Eiger and went through the carb completely. Still didn’t like to start cold. I then found that the spark was good but intermittent. Turns out the fly wheel on these was quite a faulty part and the magnets used were glued in. I decided to check the flywheel and sure enough the magnets weren’t positioned where they should be. Replaced with a new and improved flywheel from rmstator and she fired right up no matter what temp.
Good stuff, which flywheel are you speaking about
Sorry should have been more specific. The Flywheel engine left side where the stator is. The power generator for the electrical system. When the magnets located on the flywheel become dislodged it will cause the electrical system to have erratic power which often causes hard starting or a rough engine because of the lack or erratic spark.
@@evanhorst3082 did yours run rough as well?mine seems to idle fine but sometimes there seems to be a bit of a hiccup. Like it labours slightly
@@GettingItDoneRepairs This Eiger didn’t like to start and ran rough at times or would randomly shut off. I followed your suggestion and replaced the fuel petcock. I then cleaned the carb. It did hesitate so I cleaned carb again and found some gunk in the main jet. Ran great after that if I could get it started. After replacing the flywheel and cleaning carb everything starts and runs perfect. Might be worth checking that flywheel, found some other good videos on you tube. If that spark hesitates then it will get fouled out from un burnt fuel and run kinda rough. My plug was looking really black which also lead me down the spark route and checking the idle adjustment screw for mixture.
@@evanhorst3082 thank you I will take a look at the spark plug.
New subr here Roland. Great repair content. Thanks so much for taking the time to share. I was hoping you'd post the pn for the diaphragm. Was it OEM Suzuki or aft mkt?
I just bought an 04 Eiger 400 4x4. It runs and idles great, but sputters and pops when trying to accelerate slowly...like when i'm doing weed spraying. I was going to do your petcock repair, carb diaphragm, as well as a valve adjustment.
Your videos are a great help!!
Glad it helped. it is an aftermarket part I believe I left a link in the description of the video.
Is the choke leaver up or down when driving normal ? Thank you!
Sold that atv a while back. I don't exactly remember but I'm guessing up
Where did you get diaphragm from?
Love it.
Carbs are a pain. I have recently found out that I can buy new carbs online fairly cheap so I’ve done that in the past also
Where can you buy them?
@@GettingItDoneRepairs I have found them on eBay and Amazon. My friends snowblower sat all summer with regular gas/ethanol in it. The carburetor Was absolutely destroyed and I found one online for $38.
Where did you go to get specs for the carburetor?
I google it.
Thanks for sharing this fix!

Darn Carbs, they are just a problem in both food and engines!!!!! Seriously though nice DIY carburetor repair video. 😉
Lol that cracked me up! I never thought of it that way 🤣🤣
Thanks for the video
I don't function to good when I'm cold either. Thank you for visiting my channel I'm returning the visit.
Yep working on machinery when it's cold is not fun. Thank you😄
I understand this ATV... I don't like the cold either. LOL
Lol maybe that's it. Maybe its want to run down south where its warm.
@@GettingItDoneRepairs yes! 😆
👍
