So I just replaced my 35 year old, home made splitter with a brand new store bought. The old one was belt drive to the pump and in gruesome cold weather I would knock the belt off to get it started. Once the engine was warm I would put the belt back on and had no issues. The new one is direct drive to the pump of course and it went to 10 below last night and I can't get it started. Any secrets other than dragging the torpedo heater out there?
