I have never had any reason to use ether, I do know they used a lot of it on the equipment when I worked up in alaska, And destroyed two CAT engines. Simply because they didn't know to turn the start switch to the GLOW PLUG position. Once that little secret was revealed life was a lot better. I personally keep a little squirt bottle handy to sqirt in the float bowl, works perfectly. In any rate I avoid ether like the plague.
