welcome welcome! anywho, this is called unresponsive play. you must perform a bind to make it return to your hand. this is a good thing in the world of 1A yoyoing! in my opinion, just learn how to bind. cotton strings break VERY eaisily, and you shoud upgrade to 100%poly or a 50/50 slick 6 string. both work fine. if you must be responsive, put a couple drops of lube in the bearing and your good to go. i wouldnt though, because youll habe to play unresponsive in the long run if youre doing string tricks. if you lube now, youll have to clean later. that needs some chemicals (acetone, mineral spirits, lighter fluid, or if you wanna be safe and green, clean strip safer paint thinner. have fun! again, if anything your kickside being unresponsive is a good thing, work on your throw and learn how to bind!
