Wrench Cleaning your carb
--------------------------------------------------------------------------------
Looking around, I see a lot of problems with starting and
idling rough. 90% of the time it's a dirty carb. As soon as I got my Rhino home
the first thing I did was remove the carburetor bowl and clean the jets. It's a
30 min process and makes a huge difference. It can easily be done without
removing the carb from the machine.
What I did with the Rhino like I do on many other small
engines is just twist the carb enough to access the bowl.
First drain the bowl using the small screw on the bottom of
the bowl (make sure the drain tube is in a container).
Then loosen both clamps on the air intake tubes on either
side of the carb and carefully twist it on it's side. Be carefull not to pinch
any lines or pull any cables tightly.
Next remove the 4 phillips screws on the bowl, BE CAREFUL
and use a proper fitting screwdriver as they strip easy. After the four screws
are removed, you need to loosen the carb heater by unplugging the two wires and
loosen the large plug just enough to twist the ground bracket so the bowl comes
off easily.
Remove each jet carefully one at a time and clean them with
some choke and carb cleaner ( GUMOUT® - Carb + Choke Cleaner) then blow them
out with compressed air. DON'T use a small wire to clean out the jets, you will
scratch the inside, disturbing the fuel flow.
Check the bowl for deposits and clean if necessary, some
greenish buildup is common. It's Algae from this ethanol fuel.
Reinstall the bowl and tighten the four screws, tighten the
carb heater and ground then reconnect the wires. Turn the carb back up straight
and tighten the tube clamps.
Remember, you emptied the bowl so it will take a few seconds
of cranking to fill the bowl and start. To prevent furthur fuel clogging, I run
Sta-bil Marine Formula (Sta-bil Marine Formula) which is made for Ethanol
treatment. I put it in any machine that will have fuel in it for more than 2
weeks.

KG, That s the way I do mine. It is a quick and easy way to get a light cleaning. For a complete deep clean, I think You will have to take the carb off, disassemble and soak it in some real good cleaner. Stuntman explained it very well in a thread somewhere.

Yes I do think a deep clean is the best way to go, Mostly because the pasage ways inside the carb are even smaller then the jets, and if any of them are clogged or dirty it dosent matter how clean your jets are it wont run right. I use Evirude engine tuner and spray all the pasage ways and jets with its foaming liquid and let it sit for 30-40 mins to do its work. on really dirty or varnishy build up it can take longer, but it will litterly look brand new with no restrictions and thats the point. you can buy engine tuner at most marine parts stores and on ebay, It will cost you about 18.00 a can but you can do 5 carbs with it, and you wont have to do it a second time because your not sure you didnt get it clean the first time.

I always soak mine in carb cleaner comes in 5gal bucket, never tried the engine tuner may get a can to try sounds like it might be faster , also I use stable in all my small stuff

great info guys, I run startron from walmart works good, will have to try the outboard cleaner

just cleand my carb this morning and change over to 04 style intake , man was it cruddy remove jets like you said blew out with compressed air and carb cleaner runs and idles much better will have to do a little more often

Good to hear, Today's Gas is diluted with all kinds of Shit.
