1985 Spree starts and runs but won’t idle at all only runs at half to full throttle

I just picked up a 85 spree and I changed out the spark plug, new oil, fresh gas, and the petcock was bad so I replaced that as well. Now it starts and runs I drove it around for a while too but when I do start it I need to keep it above half throttle at all times or it Boggs down any advice? Thanks

Also I’m new to this kind of stuff it’s my first scooter so if you could dumb down the answer that would be greatly appreciated.

The carburetor needs to be cleaned, especially the "pilot circuit" in order to idle properly.
This is the most likely thing giving you a problem.
There are always other things that could be contributing, but pilot jet and cold-start enrichment circuit are primary suspects.
