2008 Bad Boy Buggy jumpy throttle
 

I have a new-to-me 2008 Bad Boy Buggy that had not had the throttle recall issue addressed until I took it in for some other repair items soon after purchase. The new throttle is jumpy! Some of the issue may be that I had a solenoid out and had previously been running on just the rear motor so now it's a lot peppier but the hanging pedal style combined with what feels like a much quicker onset of power makes the whole driving experience unpleasant, almost as if it's all or nothing in terms of throttle, when what I mostly want to do is ease around my farm doing chores. Is there a way to smooth things out? Is the hanging pedal the only option? Seems like a throttle pedal that hinged at the bottom would be smoother to operate. Thanks for any tips on how to fix this.
