Running a fuel additive like seafoam, lucas, etc. through it. But that won't clear up a dirty carb to well. Only way to really clean one is to disassemble and do it properly.

 

Goes back to this logic. I felt the same way you do but, when I finally got the nerve to take one apart, I was amazed at how simple it really was. There are some passages that get gummed up with goo left behind by "corn" fuel. Has to be picked or pushed out. I suggested the vent only because you said it happened "suddenly" after going through "a deep mud hole".....

 

For how easy it is to take apart any of the mikuni?? (spelling) carbs that these machines come with, it is honestly worth taking the hour and a half to really clean it out well.

If you're dead set on not opening your tool box today my favorite gas additive is seafoam.

If you dont want to take it apart then take it to a dealer and have them do it. Do it right the first time and save yourself the headache.

 

I took it apart and cleaned it.i was riding through a deep mud hole and I felt it just loose power.the rest of the ride it bogged bad.eventually it barely ran.i was just wondering if there was a way to clean it without taking it apart(took y'all's advice).it runs fine now.any thoughts as to how the carb just gummed up like that that quickly?

 

What did you find when you opened it up? My first thought was water entering through a vent or something......???

 

The next morning I drove the atv and it did the same thing(bogged)so I took the front of the carb that goes to the head apart and sprayed carb cleaner in it and it stopped bogging.then latter that day I took that carb apart and it seemed clean.so I'm confused on what it could be

 

Do u think the vent on the carb could be the reason?

 

Did you ever drain the bowl or take the bowl off? Seems like a lot of folks on here have excellent results with Startron, SeaFom, etc...

 

Wouldn't there be water in the motor If it was a cracked boot on either side of the carb.and what about the vent that goes from the air box to the motors head.just trying to figure why it did it when I got in that deep hole.

 

do you have an inline filter? how old is the machine? how old are the gas lines. Junk in the lines and tank don't get cleaned when you just clean the carb. so if you don't have an inline filter and newer gas lines the junk in the tank, and the insides of the gas lines them selves can come loose in a hard ride and junk up a carb in no time flat.

 

It's a 2004 sportsman 600. Original lines.not sure about the fuel filter(I would assume it has one but u never know)but I'm thinking the bogging issue had to come from the fuel/fuel line/gas tank because there wasn't any water in the oil or water on the air filter and no cracks in any of the boots

 

a clogged vent line will cause bogging issues without sucking water in completely too. My guess is either you don't have a filter at all (most likely the case) or it needs to be replaced. wouldn't hurt to replace the gas lines too.

Also inspect the tank to make sure there isn't a bunch of varnish in it.

 

Which vent line do You speak of?

 

Any of them. take them off an blow compressed air in them. then do a suck blow test to verify they are clear.

 

What about the line that come directly off the bottom of the carb?

 

drain tube. so that if you need to empty the bowl it doesn't drain directly onto the engine.

 

I know I'm killing you for info but how many vents can u name of hand that need to be looked at.keep in kind the bike is running great now but don't want to run into this again
