Have you checked the spark? Have you done the link and sync?

Link and sync is done and I have great spark. I thiink I need to load my gun and shoot it at this point.

Mike, If you have great spark, correct Link and Sync and good fuel and compression, I am at a loss for what could be the problem. Are the plugs fouling out? Are they steam cleaned (water in the cylinders)? Are your spark plug wires arcing to ground under load?
