the standard carb works well on the standard motor - 'performance' carbs can be tuned and adjusted to have as much power as the standard carb if you do the work - to get more power, the motor needs some changes which may allow the 'performance' carb to run better than standard carb

Remove the jet from your old NT carb and install it in your HP carb. Worked wonders for me.

Take the air filter off see if you get more power soak filter in clean gas blow it out.
Also pull your plug if it black & guiey to rich if it gray your to lean if it chocolate brown your just right.
