You'll get it all good and back to screaming around in no time.
I would recommend some kind of limiter on it this time, whether it's a rotor, an MSD box or whatever.
This is NOT an "I told you so" because I didn't and I've never even thought about the possibility of a stuck throttle blowing a motor up.
But it's a lesson we all are learning right now, at Jimmy's expense. We get the lesson for free, so take heed, people.
