So for a newbie...I can understand why using 2 can's of ether is bad in a 2stroke (no lubrication)...and spraying it directly into the cylinders is even worse....but will a quick blast of ether into the airbox hurt the engine all that much when it is -40'C....

I recently used a bit on an old genny that hadn't been run in a while, after cleaning up the plug, changing the gas, and giving it a blast or two of carb cleaner(I let it sit for a while), then a few pulls, then a bit of ether it started right up....and has continued to start over the last few days without the ether...This is an old 2stroke 1000W genny that refused to start after just cleaning the plug and changing the fuel...

Educate me please....

You might be right that a quick use might not do any damage, but the either will act as a solvent, washing the oil off the bearings, cylinders, etc, so why risk it? Use pre-mix oil/gas in a spray bottle.

To use E85 in any engine, requires rejetting and/or recalibrating the fuel curve (fuel injected systems). E85 requires a larger jet. This is due to the ethanol bringing a small amount of oxygen with it, thus requiring a larger jet to get a sufficient amount of *fuel* through to the engine.

If I were going to convert a 2-stroke sled to E85, I'd have the inside of the carbs anodized and/or coated, to prevent ethanol/water corrosion of the internal parts. Edelbrock now makes E85 carbs for automotive use and they have some sort of black coating on them to resist the ethanol. I would imagine the internal passages are all brass or stainless as well.

It would be neat to have an E85 sled. I may convert my 440 Dodge Dart to E85 with dual Edelbrock carbs if the fuel ever becomes available around here. Then maybe I will do the Liquifire after that.
