Still have week spark, 84 200s

[pikeman]

So I started out replacing the ignition coil, since it was a cheap part and it still has week spark. What would be the next part I should move on to? I see I can pick up a primary stator coil for like 17 bucks on ebay, and then the cdi for 60. I got the manual but am not the greatest at diagnosing electrical problems and I guess you can't really check the cdi anyways. So what do you guys think I should try next? Thanks.
