Spark plug, ignition problem

Im having some ignition problems i think. first questions before i post more of the problem. all 4 spark plugs are new, less then 30 miles on them. the car is not running right or starting the same. pulled the spark plugs and the top are clean as new and the bottom two seemed carboned up and carbon black would not rub off. what is the cause of this? bad ignition coils? and does this affect bad bad start up and very poor running almost blown enging no rear rotor running and very little power with servere backfiring. the problem happened 3 weeks ago, put the 4 new sparks in and ran perfect until this problem again. also the ignition wire pattern is 1 on the top left 2 top right 3 bottom right 4 bottom left. thanks for the help in advanced. if anyone is willing to pm a phone number to explain this problem and help me would be great. it very hard for me to correctly type about the problem. thanks again

First, make sure that everything is wired correctly. The locations are stamped on the side of the engine and the dizzy cap (L1, L2, T1, T2). Then verify that you are still getting spark on your leading ignition (sounds to me like you may have lost it). Make sure that both ignitors are fully plugged in too. If you still have spark on the leading then post back and we'll check from there...
