not likely.... floats set to high would cause possibly an idle issue of being to rich and to low =it'd run out of fuel to soon and stumble on heavy load situations once it started to run out of fuel but ona light cruise it might be fine.....your issue can be cured by properly tuning the accelerator pump circuit........if your looking for a simple turn of the screw and wha la it's fixed......ain't gonna happen...you first need to understand how a carb operates then you'll understand what you need to fool with to cure cruise probs, part throttle accel probs and heavy load acceleration probs...and what circuit you need to focus your tuning on...=buy the book I gave you a link too...!!!it's 20 dollars for crap sake and the info you'll learn will supercede the cost!!!
