Hey everybody. My dad bought a used Simplicity 1390, 38", 13hp B&S. The machine runs strong. The problem is that the auger control is very difficult to depress. It is kind of difficult to use. Once I get it going, I don't like to let go because I don't want to deal with putting the auger control back down. Certainly something is wrong. Is there anything you would suggest I look at? I will open it up and look for anything obvious--but I don't have a lot of snow blower repair experience--I've been a shovel man for most of my life. My dad thinks the po may have put an incorrect belt on. I have not ruled that out. Thanks for any advice.
