Use punctuation if you want anyone to understand what you're saying. I barely made any of that out.
Duraspark is a great system and there are no performance gains on a stock engine by running anything else. The right way to approach this problem is to understand why the engine wasn't running properly with the original ignition system in the first place. Otherwise, you're going to retain the same underlying problem that's going to give you issues no matter how much money you throw at it.
