Tell him not to go far and give about 4 times as much room to stop as he normally would in case the brakes have issues.
Hadn't thought of that, although the brakes seem fine. My biggest concern is trying to teach him to drive it without stalling it. I'm hoping these plugs, plug wires, fuel filter points, etc. should get it running well enough that it doesn't want to stall so frequently. He stalled it quite a few times and had a little trouble starting it Sunday when we took it out for a drive.
