Those pesky gas engines sound too much like weed wackers and chainsaws and smell like them too.. 8,000rpm does nothing for me personally either, so it's a landslide for me to stay glow. Now if they made 2.5-4cc gasoline glow plug engines for cars there might be some creedance to switch since cars are half of what I run. But I'm kind-of a die hard glow guy.
