Cylinder has spark but not firing..

Just wondering if you changed out the distributor like you said you were gonna do, and what the result was. I'm thinking the shaft is bent, after all the dismantles and re-assemblies. If you keep loosening this, and switching that you will soon forget what you have done, and you will be on dis-assembly number four, to get it all back together right. I messed with my brothers Demon forever doing all the same things over and over again, thinking I was having a stupid attack. Then I walked over to my 'Cuda twenty feet away, removed the dizzy and popped it in the Demon. Started instantly and ran perfect.
