Hello all. I have a recently installed 9hp single 2001 series, so I don’t know it’s history. Upon installation it started very easily and idled well, but trying to increase and then decrease the revs was somewhat intermittent... I have read about the term “hunting”, and that seemed to be what it was doing, but now it will start and quickly increase revs by itself up to about 4500rpm. I have to block the air intake to stop it as the “kill” lever does nothing even though it clearly is connected... I know next to nothing about diesels... Please help😩
