I've used the Ether Bunny on a 3B myself and it is quite a racket coupled with copious amounts of white smoke. I was in a campground and wasn't able to plug in my Cruiser. With all of my plugs burned out, ether was my only option. My fellow campers were less than pleased... not quite the same as campfire smoke.

The real danger in using ether is if your glow plugs are in anyway functioning they will cause the ether to ignite when you don't want it to, i.e., at a point other than compression/ignition. A misplaced explosion of ether as a piston is coming to the top can do some serious damage- say, broken crank, etc..

Some older diesels were actually designed to start on an ether charge and had no glow plugs. If you do use ether, use it sparingly and spray it into the intake quite a ways back or into the air filter assy. so that it is the ether vapour that is ignited and not the fluid.

You'd be better off fixing your plugs and doing the Wilson Switch(search)- 10.5v plugs are actually cheap. So is the peace of mind that comes with it. But in all honesty- if your plugs are COMPLETELY dead and your 3B is as old and tired as mine was and ether is used modestly - you'll be fine for a while.
