NO SPARK 305 ENGINE
Here comes a dumb question. Did you remember to put the rotor back on under the distributor cap? I actually did that once. Drove me nuts for about 20 minutes. Then my buddy held up the rotor that I'd placed on the fender and asked "did you forget this?". HTH. -Jim
Make sure that the new cap has a carbon brush installed, they won't run without it.
