Default Crank just spins, than finally starts

Hello everyone. My sons Trailmaster 150xrs has started acting up. The starter will spin but the motor will not. Sometimes there is a grinding noise. After quite a bit of cranking it will catch and the motor will spin and start and run perfect. I have replaced the starter with no change in behavior. Also, when I stuck my finger in the hole for the starter I can move the “flywheel” back and forth. I have a perfect video of it acting up but I do not know how to post it. Any help would be much appreciated. Thanks and have a great day.
