2 stroke  adly bullseye 49cc       idles fine but any acceleration the engine bogs and scoot dies out.  it did sit for about 4 months so I assume something with carburation but I am not a mechanic.  I need an easy fix.

This just happened to my 49cc. I’m going to try some carb cleaner and check the fuel filter. Could also be a bad load of gas. I’ll let you know how I progress.
1/2 way is the needle jet. Take it out and set the clip down one. That should fix if.
