Anyway, thanks in advance for your assistance.

Thank you for the reply. Let me make sure I understand. I don't believe this motor has a neutral stop. Is the "pull stop setting" the maximum throttle opening without the pull start interlock engaging? I know the pull start won't work when the throttle is full open. [links]
I assume that it should not be all the way at idle, since there would be no need for a "start position" if that were the case. I also assume that it should not be wide open, as there is an interlock that prevents the starter rope from moving when the throttle is opened up. Can someone give me a ballpark for where the throttle should be on cold starts?
Re: Throttle start position?
This code is set when the PCM sees the throttle plate sticking in an open position. Usually this is due to a faulty TPS (Throttle Position Sensor). If this code is set and the throttle plate is actually stuck open, there will be other codes set and the TPS may actually be relaying the correct information to the computer.
This code is serious in that it is a safety feature for both the engine and the occupants of the vehicle. Most likely the vehicle will fall into a default safety mode that won’t allow the engine to start. A stuck open throttle plate can lead to accidents and or engine damage. If this code is present, it’s keeping you safe. more
Replace the TPS. Commonly this will require the throttle body to be replaced as the TPS and the throttle body is an integrated unit. here
A throttle position sensor is similar to the motor cortex in the human brain, it controls one of the most important components of the car that keeps your engine running like a throttle body. Picture a little module in the car that reads how far down you have pressed the gas pedal. It gathers that information and relates it to the mass airflow sensor and the engine's RPM to make sure that the correct amount of air/fuel ratio is going into your engine properly. here
If your throttle position sensor is giving you issues, then you may have the following questions
Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow. If you see your car misfiring, Idling rough, or stalling out while you drive then you definitely want to have a professional check out that sensor. [links]

Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn't step on the gas. here
In this article, we will go over these questions and more. more
When a TPS goes bad, then the car's throttle body won't function properly. It could either stay shut or it won't close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won't start. When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle. here
If your throttle position sensor is giving you issues, then you may have the following questions
Unusual fuel consumption: The TPS works alongside other sensors to ensure that your ride is driving smoothly and efficiently. When these sensors start to go bad then other modules might start working differently to compensate for lack or abundance of airflow. In most cases when your sensor goes bad, you will see the vehicle consuming more fuel than usual [links]
