Did we already cover what it means with the choke on and the bike wanting to die? If so, what was it?

If that is the case, is my plan of action to soak the entire carb? In what? For how long? How do I rinse after?

Just to be sure if there is fuel in the float bowl and no fuel sprays out when you twist the wheel that means your accelerator pump is plugged or not working. I can't put into words how important the accelerator pump is on the modern 4T's. While this isn't responsible for the idling issue this will cause that bogging/dying problem when you accelerate.
Anyway here is what you're looking for: http://www.youtube.com/watch?v=ZbzBbLYeATw
As far as cleaning it you'll need to pull the float bowl off and follow that brass accelerator pump jet (shown spraying fuel in the vid) from the carb down to where it meets the float bowl. You will be able to spray though it with cleaner there. Next look at where that passage leads to the bottom of the float bowl. You'll see a circular part on the very bottom of the float bowl that holds the diaphragm (3 screws hold it on). Take those screws out and remove/clean the diaphragm careful not to loose the spring and such and clean all passages there. If you have a leak jet/needle near that diaphragm you will want to remove it by first turning it in all the way counting how many turns it takes to bottom out then remove it and the spring. After you have cleaned everything re-asemble being sure the leak jet is turned out the same amount as before, add some fuel and turn the wheel a few times to se if it works now. It will take several turns to prime the chamber.
Hope this makes sense. I wish you were closer it is a million times easier to explain it in person

I should add that I normally just try cleaning the accelerator pump jet (in the carb body not anything in the float bowl) first and see if that fixes the problem. This is the smallest point of the circuit and that is normally what plugs up... I do that because that diaphragm will sometimes tear when you try to remove it leaving you waiting on parts.
Anyway try that first if it still doesn't work clean everything in the float bowl, diaphragm, leak jet etc..

I understand how running lean is bad for a 2T (not enough oil = not enough lubrication = heat = damage)
Question:
Does running out of gas hurt a 2T? When you run out of gas, you also run out of oil to lubricate the cylinder. Thoughts?

Would it matter? Once you're out of gas your motor is no longer running anyways so how could it hurt it?

if you leave it in gear and you coast, the piston is going to still be moving. Plus the last few strokes were in a lean condition. I imagine the oils will still stay on the piston and cylinder walls, even without gas.
The oil in the gas doesn't burn through at the same rate as the gas. That's why you can end up with oil dripping out your tail pipe and if your head pipe is loose/bad gaskets, etc you will get oil dripping out of there as well. You won't do any damage by running out of gas.

sweet. Thanks.
If it caused damage, then every time you try to kick start your bike, you'd be causing damage as well...especially on those times that it takes several kicks to get it going.

I guess I thought that when it runs out of gas you burn up all the oil and gas. When I go to start it, I assumed it had oil and gas in there already lubing it. Makes sense though.

Well, doesn't look like ill be riding for a while. I went through the whole carb, cleaned all the jets, did everything I was told, got a new spark plug, put it all back together and it turned on for about 2 seconds. After 2 hours of adjusting and readjusting all the settings, the bike still just turns over but doesn't run. I'm not paying a shop $300 to figure out my problems on this bike so it'll just sit in the garage while all my friends are out riding. Thanks for the help everyone. Looks like I bought an orange lemon.

There has to be something specific happening... sometimes you have to bite the bullet and pay to get something fixed. Pay up, then go riding!

My opinion, don't take it to a shop like Motofrugals, take it to a real shop that really knows what they are doing like The Edge or even South Valley. I bet it's $150 or less to get it fixed. They'll dial-in the jetting maybe replace a jet or two and you'll be on your way. Learning on a carb that's potentially completely out of adjustment is a tall order. It's easier to have a good running bike and tweak with it and see how each thing makes it behave. Learning by what others tell you on a forum is difficult.

In not totally giving up. Just down on my luck. Things always go wrong with stuff I don't know. Go figure. Ill give the edge a call tomorrow. I'm just scared that if I go in there ill end up trading my bike in for a newer bike.

Nothing wrong with that.

They are out of 300 xc's
That's not a surprise. Did the AFC Edition one back by the sales counter sell also? It was several weeks ago that I was last in there, I'm sure given the weather and time of year the selection will be getting smaller and smaller.
