Yes, the first proceedure is a good thing to do.

A blocked vent in the gas cap will cause it to stumble and die after running for a couple of minutes. Up to that time, it should run fine. From your description, I don't think that is your problem.

You DO need to run it a bit to get the cleaner through the carb. If you can't run it up and down a side street, letting it idle for 10 minutes every couple of hours might work. (Don't idle it too long or it might overheat.)

I'm thinking you need to save up your $$$ for a trip to the shop for a "real" carb cleaning. Ask first but should be about $100-150, and get a fuel filter installed.
Yes, poking wires into jets is not a good thing to do.......for an amateur.
