What are guys doing when starting their sleds inside? Does anyone hook up a hose of some sort to the exhaust and run it outside or does everyone just open the doors? Wondering if anyone has had any good luck with anything in particular... I want to start my sled inside without opening the door to cool off my sled shed... I'd like to keep some heat in there when I am wrenching and not die from carbon monoxide posioning is also a plus... Was thinking I could pick up some drainage tube or something and just run that out side Any hints or tips would be appreciated... Thanks.
