AV8TOR, There is about 2-3 inches of snow here in West Michign. I fed My Husky Dogs and thought I would see how my Gas/Glow test engine would start. I put the glow driver on for about 30 seconds..fliped engine over with my thumb to it kicked back a little. Then I gave it a serious flip and it started right up. It ran smooth on Idle for about 45 seconds and then I took the glow driver off. The engine did not hardley drop any RPM and it kept running smooth. I shut it down and it re-started first flip 3 times in a row. By then I was frooze...end of test and back in where its warm. Looks like cold weather may help engine...but not me! Take Care Capt,n
