I recently purchased a 461 and a stihl edt9 tachometer. I would like to adjust carb to fine tune it to make sure it’s set up right. I recently put on the double port exhaust cap. I tried to adjust carb so far with tachometer and the numbers are constantly changing is that normal and what are the average rpms it should be set at 2500 and 13500. Thanks for any help
