pull the middle wire off of your distributor cap, it should be coming straight from your coil, place it near a ground, or your block, and have some one bump the motor over. you should see a nice bright spark jump. if it is weak or not there at all. if there is a strong spark, then place the wire back, and pull one from a spark plug and repeat the process. if the spark is weak at that point, look in to your points, condenser, cap, and rotor. or possibly your plug wires. if the spark is still strong, check your spark plugs. and make sure the gap on them is correct.
