CVK stands for Constant Vacuum Kiehin. 24mm is the correct stock size carb. 30mm DO NOT improve the performance of stock unmodified gy6 157/152/1p57 as they are too large. A 30mm FLAT-SLIDE carb is for a gy6 with engine mods, such as a significant BBK.
The cheapest and easiest way to get optimum carb performance is with a an open-element air filter and a larger main jet ( #110 to #125 for UNMODIFIED gy6 152/157/1p57) the 24mm is more than large enough for a stock engine.
