Buddy’s intake has an air cutoff flapper. First winter he had it, was bouncing around, and flapper closed.
Had no idea it was there. took him a while to figure it out.
The Emergency Kill on one of our truck cranes got pulled mysteriously. I do my morning walk around jump in hit the starter button and nuthin' but crankin' and wee little wisps of black smoke :wtf:. I was just an apprentice but had some history with Detroits. Checked the kill switch normal, open up the hood again, sure as life the flapper had tripped to the OFF position. The spring on that flapper is pretty stout and no leverage on that little cam :lol: The carpenters were a little upset with me after we rolled up 15 minutes late :rofl:
