The reason I said 30 sec, is that Ive noticed in mine with the change in ambiant temp, I know have to heat mine a bit longer, like 15 sec. All summer long I just had to touch mine 5 sec, starts right up.
I can remember when I stripped coal in western pa, some times Id heat the engs on our 777 for half a cigerete. Still didnt want to start it was so cold. But thanks to global warming, and more techonlagy, those engs dont have to be heated so long!
