Sometimes valves that need adjustment can be a source of starting troubles.

2nd I would pull the tank dump the gas and look inside with a flash light. If theres gunk in the tank then theres probably gunk in the carb.
3rd you can pull the carb off or slightly loosen it / rotate it enough to get at the jets with out pullind the whole thing apart. Does make it easier if you disconnect the subframe down by the pegs and rotate it up towards the tank/bars. You can get to the bottom of the carb and clean it out, and pull the jets, clean and record what you have in there.
Often a plugged pilot jet will keep it from idling and will pop and back fire if you try and ride it.
4th the choke should be pushed in for off and pulled out for on. Hot start will be your red knob, same thing for positions.
Lastly hard starting can be a sign of valve clearance issues. But try one thing at a time.
Good luck and get that manual or have a TT member make some copies of needed pages before you do anything.

Did three (really two) things that solved the problem:
1 & 2 Make sure the gas is fresh and the tank has enough. The WR tank drops below the petcock on the right and will seem like it has enough gas, but not really.
3 Make sure the carb is clean. Check the float and the accel pump bowls and make sure the jets are clear.
Throw in a new plug, follow the starting proceedure (check posts or ask) and, assuming all else is good, it will start with ease.

sounds exactly what was happening to me and turned out to be dirty fuel ( water ) but i was reluctant to suggest that given my limited know how and not wanting to sound too simplistic.
heres what happened to me
and this, the ol' plug thang
I can ride a bike and steer a computer, but cant fix a bike.
hope this is of some help.

can someone explain how the choke button "should" work.. mine seems to be sticking out.. im not sure if its sopost to be sticking out as far as it is.. is there a half way open position? thanks
Maybe I am reading something wrong here.
You say the choke is sticking out. Are you sure that is the choke and not the hot start. The choke should pull up and down, the hot start should be side to side(in and out). If it is the hot strat you are using that would be your first point of being lean. Just a thought.
Clean the carb and fuel system and check and adjust the valves.
