When in the mustering game used to start H-300 C's seated and then exit to check for oil leaks and to warm up the body near the exhaust (christ it used to get cold in the mornings) and once it was warmed up get back in strap up and then engage the clutch/rotors and away. Never started a machine like this bloke,,asking for trouble me thinks...
know a person that engaged the clutch on a 300 while outside and stalled the engine,,, didnt realigned the drag on the rotors, as a result on the restart and re-engage of rotors got ground resonance ( was in the machine this start) and the machine killed itself....LESSON learnt.
As some one said,that was a long start,,dont think that starter/geny is going to last to much longer
keep em in the green
