Removed the old handle half that was left and the right side that is attached to the upper handle . Removed the torsion mount springs and the air filter housing . Transferred all the necessary parts then installed the new right half with the upper handle and then the throttle lock and trigger with the return spring which was slightly confusing when the old parts were missing so I used the parts breakdown from e replacement for the placement and finished assembling the rest and the repair was successful thank you, all the part were right the first time around
