amt31,
Since your brother didn't mark the wires, I would start with the plug wires. The igntion timing is most likely off and the engine will not run until the timing is set correctly. In my earlier post I tried to give you some help in checking the wires. Provided that the distributor was not removed it should be fairly easy to correct the problem with the plug wires. However, since all of the wires were removed and not marked you are first going have to get the #1 cylinder on top dead center. When cylinder 1 is at top dead center the distributor rotor will be directly under one of the six spark plug terminals on the cap. This terminal will be the terminal for the #1 cylinder and the wire leaving this terminal is connected to the spark plug on the #1 cylinder.After you have got the plug wire for number one leading from its terminal on the distributor cap to the spark plug for cylinder number 1, the rest of the plug wires can be installed. Just keep the firing order and clockwise rotation of the distributor in mind when you wire 'em up
The following post will give you some additional help with setting the timing on your engine.
