I had the same problem so I spoke to the folks at Feldmann Engineering (they make the Jiffy Augers) As stated in another reply, the engines are set-up at the factory in warm weather/temperatures. This makes them run way to lean in cold temps. Feldmann recommends that you "turn the right cap (red caps on the carb) counter clockwise 1/8 - 1/4 of a turn. This will allow more gas into the engine." I took the red cap off and adjusted the mixture screw. My auger works much better now and I no longer curse Jiffy while trying to start or keep my auger running.
