I've rebuilt 200x carbs, they are about the same carb except the 200s came w a 22mm keihin instead of a 24 like the 200x did. What info are you wanting exactly??

You can order the Moose card kit #17-1340 from www.denniskirk.com for $14.95.

The main thing to do when rebuilding the carb is to count the turns on the jets. So you can be sure to set it close to what it was before. But if someone has been tinkering with it then the settings might not help you at all. Do you have a manual for it?.If not i cound find the jet settings for you. So yuo would know how many truns they should be set at. Other then that it is just a matter of getting all the gunk out of the carb. Get a big can of carb cleaner and spay the heck out of every thing. And i take a twist tie off of a bread wrapper and burn all the paper off of it. It works great to stick through all the small places in the carb to get any gunk out. Good luck.

1st thanks
2nd you gave me alot of info right there on the carb size,
I have a couple of spares for 250sx.. could they work??

I need all info you can spare, take me by my little hand ( that has only thumbs on each one).

and tell me what you know, where can I expect trouble and how can I avoid it

again thanks

LOL. well you can prob expect trouble out of a 250sx carb since it will definately be larger than the 22mm keihin. Don't hold me to this but I think it was a 27mm, I wouldn't want to stick anything bigger than say a 24mm off a 200x UNLESS you up the compression, put a cam in and pipe and other things you would really have to jet it down for it not to overgas it I would think. Youd probably have 30 bucks of jets bought before you get it right. If you have beefed up the motor somewhat then go for it. Others may correct me on the exact carb size of the 250, but it is definately bigger than the 200's. Dan should be able to help you w/ the 250sx carb size. Fuzzy's idea about the twist tie wire was a good one, I would also reccomend an old toothbrush to scrub on the inside of the carb they get really gunky. Even better would prob be to take it all apart and soak it overnight in a parts cleaning solution, and then some scrubbing may still be in order. parts of the bowl down by the drain are nearly impossible to get to w/ even a toothbrush, be nice to have a smaller one even. And buy some spray carb cleaner, I used two cans nearly on mine.

The 250sx calls for a different carb kit. I dont know what the difference was. Maybe it was a bigger carb. Or a totaly different design.

The main thing to do when working on a carb. Is to have a clean dry place to do it. And to make sure you dont loose any parts. Once you get it open you will see there isnt much to them. There is nothing that has to adjusted inside the card. You just pull out your old jets and screw the new ones in tight. And before you remount the carb on the trike. You want to adjust the idle mixture jet on the bottom front of the carb. Because they are a bugger once you have the carb mounted. And the one on the side of the carb is for the idle air mixture. And that just lifts the slide up in the carb some so that it will get some air when ideling. But it is not a crusal setting. It shouldnt take more then a few minutes to take the carb apart and put it back together.

Fuzzy,
you mentioned something about the jet settings and that you could find out what they are? then mentioned in the next post was that to screw them in tight. are you still talking about the same thing or are the settings part that you are talking about the ones to the screw on the bottom of the carb?
i got a 250ES does that have the same carb as any of the others? you said on the "idle mixture jet" that to set it before you mount the carb because of it bieng hard to get to when mounted. what are the settings? i guess that would be different for each carb huh? :shrug: is it a matter of how many turns in and/or how many turns to back off?
Just trying to learn as well.
Thanks, Howard

[Fuzzy]

Yep you are right. The ones outside the carb are adjustable. The main inside the carb is not it just gets tightened back down.

And gereral on the 200 motors te pilot jet setting in the front underneath the carb is 2 - 2 1/4 turns out. So just turn it all the way in gently until you fell it hit bottom. And then count 2 turn out. And as far as the idle speed on the side of the carb. Just start it up and turn it in if you need the idle to be higher or turn it out if it is raceing. And then let the motor warm up for 5 or 10 minutes and then readjust the idle speed again. Until it idles good. And you are all set.

Do you just happen to know what it would be on the carb for my 250ES big Red? 1986 model.
Thanks, Howard:thumbsup:

I would imagine it is probable similar. But i dont have any manuals on the 250 engines. Maybe make a new post here in the tech section. I am sure some one here has rebuilt there big red carb.
