Girlfriend just bought a new 48cc from bikeberry. A bbr tuning kit. I installed it for her. On my bike, I've got an old grubee skyhawk that once I put on a new nt carb, runs great. Hers, not so much.
Get it going and release the clutch, the engine turns over. Flat land is ok, but not much power. Going uphill and you have to pedal, the engine wont even try. Also, engine wont idle. Even with the idle screw all the way in. Now, it will idle if you hold the throttle, so did that and checked for air leaks using carb cleaner. Had one at the carb/intake, sealed it. Now I cant find any other leaks, and engine still produces no power.
I swapped carbs. Hers works great on my bike, and with mine she still gets the same problem, so it's not the carb either.
Running a 50:1 opti-2 mixture in both bikes, always have with no problems.
