I have a propane start K 80 with 6.5 hours since service last year. It gets up to 22000 rpm and shuts down and gives a start bad message. The starter motor doesn't sound right and i had a couple experienced turbine guys look at it this weekend at our jet flyin. They both said it is a starter problem and i should change it out. Does anybody know if it is a replaceable item that i can buy and fix myself or will i have to pull the engine and send it in?
