When it's below 25 degrees my 259D has a very hard time if at all starting. It's a new to me 2018 with 230 hours, hasn't even really had it's 1st service yet. I keep it plugged in when its cold and the advance display reads the oil temp about 50 degrees. Fuel is good, no gelling. The machine just wants to keep turning over but not firing. If it does fire, it runs great. No sputtering or lack of power. Looking for any thoughts.
