I want to know the most accurate and easy way to adjust it. I know many have said to install it, tighten it finger tight, start the motor, back it out till you hear noise, snug it up until the noise goes away, then lock the jam nut. I WANT TO KNOW FROM THE PEOPLE THAT HAVE INSTALLED THE MANUAL UNIT, HOW YOU ADJUSTED YOURS???I don't want to put it on and lock the motor up when trying to adjust it!!!!Any help will be appreciated by many!!
