Serceflyer,

Sorry, missed your other questions.

Virtually any brand quickstart will work, in your prime OR your tank, I've tried two others, house brands from local automotive outlets. If NO ether will run, then ANY amount will help. JD is 80%, if you had a brand that was only 50%, no problem, as long as you get her started and running. It's just a matter of adjusting for what you got in your particular brand, even though you don't know what that is.

Spring starter? Yes, as shown here. http://www.youtube.com/watch?v=af4dQNa60_w

The audio is out of sync but note that I started this Norvel by priming only by way of blocking the muffler to get fuel to the carb. This, of course, was on my then standard fuel of 40 ether, 40 kerosene and 20 castor with 2% Amsoil. This was an .074 so I had to adapt a Norvel .06 spring starter. Because of the bend I had to put into it to secure it to the mount, the spring failed eventually and I haven't had a chance to install another with a proper soft bend in the right location. So, I haven't had a chance to start and run a no ether fuel using the spring starter but look how easily it started with normal fuel. I'm speculating that, as the engine starts with a high ether prime on the electric starter, it should be fine on the spring.
