WOW;;;;;;;hope that doesn't happen to mine when i get to start it for first time;;very lucky man there.looks like his face was over top of hat when it came off
it gave close up very qucik toward the end of the video..i justs wonder if they had the correct size Burst panel..if any..i know this doesn't guarantee this from happening but it helps out...at least it looked like they had the aluminum pop off studs holding the blowing to intake..IF NOT it could have turned into a Grenade for sure.
I know its a guess here...what do you guys feel went wrong here for the backfire....Cam comes to my mind 1st off..one thing is something exploded in the top half of the motor..
