Something I haven't heard mentioned yet is the anti-backfire valve on the bottom of the carburetor; it's a spring loaded electromagnet which pulls a plunger down to allow fuel to be brought into the jet of the carburetor. If this is defective or has a bad ground, it could be only partially retracting which would allow some fuel into the main jet however under load, it would starve for fuel. Many times, you can simply replace this with a bolt to hold the carburetor bowl in place. It is energized while the engine ignition is ON.

If I buy that new carb someone showed earlier from Amazon, I won't have to worry about that correct?

They are hit and miss; I've had better luck with OEM however that's just me. It was just an idea to verify that it's the carburetor and not the solenoid. I would still take the carburetor bowl off and see if there's any crud in there. The ethanol in fuels creates a gel and attacks the aluminum in the carburetor when they sit. You can check to see if the solenoid is sticking/stuck.
