Ether in a 2 cycle would be a really, really bad idea. If it was life or death mandatory, then perhaps... ether.
what would happen, if ya snorted a shot of ether right at the compression release, chug the motor over. close the compression release? Would any be sucked directly into the cylinder to help the next ignition? This would have the advantage of getting ether directly into the cylinder and not down in the transfers, and bearings (bad things there).
Fuel with lighter carbon chains would be better, in this situation. 12 drops of coleman fuel...?
Properly tuned, decent compression, a saw "might" start. Most likely the problem would be getting fuel to atomize and get it all the way from the carb to the cylinder. If the motor is stiff to crank over, this would compound the problem.
Once the plug gets "wet" the party is over.
I have "cut" some at 0 deg, Not a lot of fun.
at -15, I am with the rest of the crowd. I don't start any better than the saw does.
