The valve adjustments definitely helped. I will change the pilot jet when it comes to hopefully fix the choke issue. I attached a photo of my pilot jet and carb. Thanks everyone for the help!

Yep, Delta, OH is only 122ft higher than me; guys using a 135 ish main are the ones with head porting and cams, higher compression... that's WAY too huge for a basically un-modded CG250. It's masking the problem, not fixing it.
Your issue lies within the pilot circuit, not the main. Fixing that will likely take care of your 5th gear issue as well; doubtful you're only running half to full throttle in 5th gear. Pilot circuit and needle jet are the main fuel delivery at this point.
