Exclamation Work Log: DIY Engine Maintenance (Newbie Perspective)

NOTE: Formally entitled "Possible fueling issues?"

For the past week I can smell a hint of fuel through the vents if I give it 50% throttle even under 3k RPM.

Throttle lag is one thing, but I'm starting to notice more defined hesitation or bogging under 3k RPM even if I floor it. Plus, power delivery is a bit lacking and feels rough from 50% throttle onward. I have to rev it past 3k RPM to make some power and get it going, but it definitely feels like it doesn't want to open up.

In the past year my engine has died twice after coming to a complete stop (most recent was a few days ago). Engine would idle fairly low or want to drop (closer to 500 rpm). I occasionally have trouble starting the engine (as described in the past), and from reading I wonder if it's vapor lock.

I'm wondering if it's the stock FPR at this point.
