Hi all, new to the group. Been using an RBI Hawk for about a dozen years or so. Love it and it has worked great. The other day it started "missing" when I changed speed with the knob. I know it's electric powered, but it will stutter and "miss" for several seconds when changing speeds like a car with bad fuel. Has anyone had this problem? I'd like to fix it, but want to avoid just throwing (expensive) parts at it.
Thanks
