the gas is new, the hoses are on, the and the battery is also new. known problems: the tank is internally rusted, and there is a small 1 inch spout running from the back of the tank that has a hose running from it to I don't know where. When I start it in Neutral, the choke is on, and it runs fine. The problem is when I rev it up, it bogs down. What can it be?

Sounds like the all-to-common "Water in the fuel". Drain your float bowls into a glass jar and look for a murky liquid at the bottom of the jar. there's a basic how-to over here:

That's with the (rather generous) assumption that the bike was running fine less than a month ago and NOT stored for a long peroid of time with this being your first attempt at getting it going again. If this is the case, you need to clean the carbs (or pay someone else to do that for you). And next time you're not going to Ride the bike for more than a month, drain the carbs to keep them from gumming up.

You have a fuel/air problem. If your airbox and boots are all connected properly and you haven't messed with the stock exhaust, then it is a fuel problem. Your bike takes less fuel in neutral then when under load which is why it may be ok at idle. If your tank is rusty you can bet your petcock, carb bowls and jets are full of it. You will need to have your tank cleaned and sealed. (I have had great luck with POR products)
Carbs need to be pulled and cleaned. By cleaned I mean removing every single jet, removing the air screw caps and air screws and so on. Some jets may need to be replaced because they may be plugged. You should leave this to an expert as I've seen people damage the slides and other parts and run up hundreds of dollars in expenses. When you have the carbs off its a good time to set the valves. Run a compression test and make sure the carbs are in sync. Then go out and beat up on Hondas.

Sounds like the choke is not letting enough air in. I've had this before - its usually a minor adjustment. And if it cuts out when you put it in first, I'd look at the kick stand switch first. This is a small switch that prevents you from riding off with the kick stand down. However, if the switch is not working, or if the return spring is weak and the stand is not pressing hard enough on the switch, the bike will kill the engine when you put it into first.
Good luck, and keep it upright!

well the only thing I know that it could be is the timing. I have only done repairs on a 1973 yamaha two stroke so things might be alittle different. When it was rideable were there any problems? You would know if it was timing if it acted really weird. try doing everything, take the carbs apart and look at them, then sync them. The ignition timing could be bad, my bike hadnt been used in years and the timing got really bad and right when I started off it would bog no matter what (even working the throttle) and cut off. It probably isnt any of that or you would have stated that you heard strange noises. good luck with your bike, hope its something cheap/easy!

This could be many things, from dirty needle valves, dirty jets, air-fuel mixture not set properly, to stopped up fuel rail between the carbs, to vacuum leak at the tops of the throttle slides, to improper hose routing for the fuel advance on the petcock. Best thing to do is take it to a shop and have it diagnosed.

Adjust the fuel intake, Tha 1 inch spout runs to the carb. which needs to be adjusted too, mine did the same thing a month ago. Also try a fuel system cleaner, they are very cheap.but effective.

Maybe your clutch is bad. If it happens when you put it in gear.
Could be bad gas, when gas sits ... you probably know this, but it gets gummy.
If your tank is rusty well... duhh....maybe your fuel injection is getting clogged, it is fuel injection right? I know my carb on my Yamaha dirt bike gets clogged if it sits for a month or more without draining the fuel.

To much gas going to the choke,you are flooding the car out do not pump the car more then three or four time to stop it from flooding.
