when running 75% or so throttle the motor runs good but when pushed pass the motor starts to miss fire an start runnin funny i was think spark plug wires would that be a symptom from bad spark plugs
Probably not a spark plug issue if it was it would usually run ruff through out a wide range of RMPs. Might be a carb issue, when was the last time they were cleaned?
check timing advance , vacuum or computer driven ?? -could cause to break up .. as earlier rev-limiter ?? -mis fire, run funny - fuel filter @ wot = run funny ? mis fire @ wot = timing ? -anytide
