Just changed the plugs. Here is a pic of what the old ones looked like. It's a wonder it even ran (especially with #7). The squirters are also 45R-312, but I cannot find that part number on...

Even if the power valve is not blown out, do they still go bad? If it is bad, it would make sense why it is running so rich. I'm not sure if it can be the root of the main problem of the severe bog...
