[big job]

I'll never forget this. Way back in high school we had a flathead that had the same problem you have. Teacher said 'lets play detective' . Us kids smoked our brains finding nothing wrong its impossible. After all said and done, teacher said the problem is right in front of your nose -open your eyes! We all gave up. The teacher made lines inside the dist. cap with a lead pencil!! gotta be kidding Now thats real teaching.
