if you didn't put anything in the gas, then let it sit for 6 months, the pilot jet is plugged. Guarantee it and it cannot be fixed. Replace the carb, they're cheap. Do a search and you'll see many have tried to clean them (my son is one) but there are too many tiny passages.
I see you're in CA so you're getting ethanol in your fuel if you use regular, it is hydroscopic (attracts moisture) so if you don't run it then the fuel evaporates and leaves the moisture behind. did you pull the float bowl (easy to do)? If there's white residue then that's your answer. You experienced part of that when you started it last, "runs up and down". At that point it might have cleaned itself out if fuel system cleaner was used, but it sat and got worse.
