What a life saver this video was. My Mercury 9.9 HP suddenly started dying after running for a few seconds. I was pretty sure it was the carburetor but I was unsure about how to remove it, let alone how to dismantle it. Thank you.
This video saved me probably $200 -$300 in repairs. After checking the spark and seeing that the fuel was getting to the carburetor, and still not starting, I followed these very detailed instructions. After reinstalling the carb, the motor started on the second pull.
WOW, this video was a great help. I have a Tohatsu 9.8 4 stroke. I put Tohatsu 9.8 into the search and it gave me this video along with some others but I have to say that the engine on this 2005 merc looks the same as my Tohatsu 9.8 as does the Carb. The instructions were great and helped out a lot. Thanks!
I can confirm this procedure works on the 15-20 hp four stroke mercury late models as well. The inner mounting bolt for the carb is not accessible from the front like on this smaller motor, but you just have to remove the intake manifold/carb/air intake as one unit and it goes easy as pie.
Thanks, great how to, will reinforce classicoutboards , wear eye protection when spraying, also having used petroleum products for many years without gloves, I eventually got skin reactions in later years, wear nitriles or latex, your partner will appreciate it too.
I tried this (2007 9.9 Merc 4St). Very informative video. I wasn't to thrilled on the idea of tearing out my carb, but after seeing this done, I wasn't too worried. My motor would do only high rpm's but no idle or run at slow rpms; Carb was fairly clean but I did notice some debris in the tiny little pin holes that drop fuel/vapor into the chamber. I did remove the mixture plug cap; and clean that too, everything that would come off; I took it off. Only issue I had was putting the air intake gaskets back in; the 'choke' would very slightly touch them when pulling it out or in. Had to finally trim/file the gasket and plastic manifold part to allow full choke to work. It's late; and I haven't started it yet, dont want issues with neighbours, but Ill post more later. THanks for the video.
Great video! I would wear rubber gloves though because solvent isn't good for your skin to come in contact with and can lead to stuff like testicular cancer in young guys.. Had a friend this happened to, but he made it through it.
thank you for the video it was very informative. i noticed you did not take out the cover Diaphragm is there a reason for that ? i took mines off but i am not sure if it has o rings or a gasket because i got it to run but now its leaking fuel from that area, specifically by the screws. can you assist please
Hi, I have a problem with my carb as well, at 5:51, the small jet. does it have to be like you can see through and through at the hole? because mine I cannot. does it mean it is clogged? waiting for your fast reply. thanks.
Baron, terribly sorry to reply so late, but my suggestion would be spray through it until you can see light through it. You may need to take a small wire and poke it a bit. My kids are in college now.
I am right there with you Fritxmerde... Great video, definitely schooled me on cleaning my carb! I am having the exact issue motor fires up and as soon as my i give it fuel it bogs and dies. Did you get the answer to your problem last year?

Many thanks, got it done in an hour

Perfect, I have that exact engine and it seems that it's not getting enough fuel. I expect this will be just what it needs. Thanks for sharing

Helpful video. Good music at 5:14
Great video I couldn't get decent info anywhere else, as long as you know whet 'dese and 'dose are you know what to expect. Thank you.
Awesome video, about to get started on my 2001 9.9hp.
Where is the idle mixture cap exactly? Needless to say this video was extremely helpful and my 2002 9.9hp runs better than ever. Great video.

Great video. This really helped me. Thanks
Great video. I'm going to try it out!
i have the exact same problem, it seems like its going away the more i run it, but still there, would love to know why if anyone has any idea

I have a Tohatsu 8... This looks exactly the same...gonna do it right now...will let you know how it goes.
So.... how'd it go?
@rasm146d Yes, the procedure is different for removing the carb and disassembling it, but the cleaning process is the same
nice video .helpful man
I have a flooding issue. Is the seat in these carbs removable?
ever thought about putting an electric starter on your 8hp? what would you need?
Thanks for posting, this was perfect. Have you taken the lower end off? I have the exact same motor and need to replace the impeller - thanks

after you sprayed the stuff all through the carb how long did you wait for it to dry? or did you just put it on right afterwards?

wear PVC rubber gloves when you spray that stuff because it's toxic and does absorb into your skin
also, make sure to wear eye protection when using carb cleaner, it doesn't feel good in your eyes
first unscrew that and uh that and uh take out these two things lol nice vid
you forgot to pull the idle mixture plug cap out and clean the passage, major problem with these carbs
i found it's alot easier using a 1/4 inch drive to remove the carb.
why not show how to mount and how it regulates....?thanks anyway
That, that and these two "things"??! Oh... ;-)
that& That
& That& That.....30 minutes later and That!!!
