Verify fuel flow to carb . . overfilling the gas tank may have obstructed the vent canister.

Troubleshoot vacuum leaks by looping the 2 intake manifold ports together with a hose.

Observe if carb slide is rising properly.

how to make my machine run at it's peak performance

Based on your previous postings . . you have already cleaned the carb, adjusted the valves, changed engine oil, and added a gas additive. No mention of inspecting variator weights, drive belt, or re-greasing the torque driver.

YouTube is an excellent research resource . . example.

grease the needle bearing inside the clutch

Torque driver guidelines. Walmart Super Tech grease works fine.

If you are open to experimentation . . consider placing a loop of Teflon valve packing in the stock spring base channel to ease twisting movement.

Roketa Tahiti 150cc stalling and dying when stopped . . cleaned the carburetor . . adjusted the idling speed

Verify intake air filter is not obstructed.

Adjust low-speed mixture screw on side of the carb (below ° vent tube) around 2 turns out.

Check valve clearance. Test cylinder compression. Consider replacing intake manifold and insulator to deter vacuum leaks.

gas started leaking out of a tube on top of the carburetor

That port vents the carb fuel bowl to atmosphere. The carb float needle may not be seating properly. Might try tapping the carb with a plastic mallet or screwdriver handle. If no joy, carb will need to be disassembled.

Consider adding around a tablespoon of Iso-Heet to the gas tank and rocking on the center stand to mix with any stratified water.
