Air Vents plugged

[mikewilson30]

The air vents on the rear of the head on my CL 72 are plugged up. Any advice on how to open these up. Where do they <br />end up? Crank case or intake ports?<br />Might this be a clue to why it backfires when decellerating?<br /><br />The plastic tubes went to the air cleaners but the new ones air cleaners I bought don't have a connecting nipple. Did Honda make changes in where this tube is supposed to go if it does not go the air cleaner?<br /><br />Mike
