Drain the fuel and put new fuel in from a different source. Its the chaepest thing you can try. I had the same problem the beginning of this year. I run alcohol but it would only pop at the top of low & high gear. It was a brand new barrel. I tried and changed everything and it still popped. I was at Memphis and had to buy fuel and believe it or not it quit popping. Try It! Don
