Have an issue with idle! Starts perfect, accelerates well, but after a few hours of haulin' the fuel flow feels erratic. Idle seems higher and often gets more blow by from the breather tube. Oil also drips but seems like a mixture of oil and fuel. Any feedback? Replaced puff limiter on intake and on the pump, new fuel lines, and filters. Don't get any smoke out of exhaust.
