When I apply carb heat at run up, I get very little rpm drop. I had the valve checked and the valve closes about 90-85%. Is it supposed to stay a little open? I am used to 75-100 rpm drop with Cessnas that I trained in. My mechanic is not concerned but I am curious as to What do you all get? The plane is a PA28-161.
