Jerking hard from idle to acceleration

[ToddC]

Hey guys!! Need a little help please. Just bought a used 2022 Coleman GK200 for my son and it’s jerking really hard from idle to when it starts accelerating. This happens in drive and reverse. Any help would be greatly appreciated!!

It’s against the rules to multipost about the same problem.
