what did you clean it with? maybe its still gummy. i'd take it apart again, clean everything with gumout carb cleaner. make sure the float moves freely. also maybe also the cable is a little jankie. just a thought. sorry your so far away, i'd give ya a hand.

Others poo-poo them, but I love the cheapo eBay replacement carbs. I have been using one since April 2010 with no issues. I don't bother rebuilding old carbs anymore unless I absolutely have to

I've had the 'w' clip that holds the main needle down inside the slide flip over so the
main needle settles wherever it wants to. and also missed it a few times. Very common.

It's held down by the return spring inside the carb/cable IF it's set in there correctly.

Many people also have your 2nd problem of not getting the main piston down all the way into the carb.
so it revs really high.

I wonder if the cable jumped out of it's hook inside the handlebar assembly when it was too loose.

Nothing real complicated, just frustrating
