Hi ....OK explain this one. I have been getting little burps out the tail pipe going down hill coasting.....some loud backfires. I figure the Rodchester B needed the little mixture screw turned out for a richer mixture.....no deal no matter how much it moved out same old story....BUT.....I decided to turn it in and now the burps have gone away. I was told that I needed more of a rich mixture instead I leaned it out and so far no burps or backfires.......WHY?
