Trying to get a friends 200sx running but won't start. It had run but been sitting for a few months. I pulled carb and it was pretty dirty. Cleaned it up with carb cleaner but didn't help. It is getting spark and has compression. If I spray some starting fluid in it will run for a few seconds and die out. I put a new fuel line on and it is getting fuel from the tank. After it dies from the starting fluid it spits some gas out of the back of carb. I set the fuel/air needle at 2 turns out. When you take the bowl off the carb there is a large jet and a small jet. The large jet has a whole that goes entire way through it. I know that is correct however the small jet is not hollow whole way through. Should it be or is it clogged? Not sure what else could keep it from starting?

Welcome to the forums. You are on the right track. The carb is stopped up. Both jets have holes all the way through. Sounds like one is clogged. Also, I would remove the pilot screw, both jets, and float and float needle and blow air through all the passageways in the carb body. Be careful when you remove the pilot screw and don't loose the tiny o-ring, spring and tiny washer. Most of the time, the o-ring will stay down in the hole, so make sure you dig it out before blowing air through the passageways or you will loose the o-ring.
Thanks. I was able clean it out with a thin wire. It was definitely clogged shut. I think I really just need to soak the whole carb in some sort of cleaner. Spraying with carb cleaner and compressed air just isn't doing it. Any suggestions? Obviously I know to remove rubber o rings.

You can get some carb cleaner that comes in a gallon can from the auto parts store to soak it in. It has a basket that you set the carb in and drop down in the can. I can't remember the name of it, but any auto parts store should have it.
Here is a link on cleaning carbs that you might also be interested in. This guy actually boils the carbs in water or lemon juice. He says it works better than carb cleaner, but I've never tried it myself.

I didn't get a chance to soak it and my curiosity was killing me since opening up that clogged jet. So I decided to put it back together just to see if that was the problem. I also didn't really want to put all that effort in just to find out it had some other more major problem. I put it back together, barely cranked it over and it fired up and ran like new. Amazing how well it runs. Idles smoother than most newer bikes I've worked on. One last question... Is there an easy way to clean the dirt out of the tank? Do they not have a fuel filter? Thanks.

Glad you got it running!! The only way I know of to clean the tank is to take it off and pour a little fuel in it and slosh it around and drain it out the top. The tank just has a screen in the tank that attaches to the cut off valve. You should be able to remove the cut off valve and pull the screen out. If you want to, you can add an inline filter in between the tank and carb.
