Cool

Surelock. Since I don't know what your education is with regard to 2 stroke engines, just in case you're wondering why you shouldn't use starting ether in a 2 stroke:

In a normal 4 stroke engine cycle the fuel/air mixture is sucked directly from the carburetor, through an intake valve, into the cylinder, where it's burned, then exhausted through an exhaust valve. It never gets into the crankcase of the engine.

But in a 2 stroke engine, unlike a 4 stroke, there are no intake and exhaust valves. The fuel/air mixture is sucked from your carburetor, through a one way reed valve, into your engines crankcase, and from there into your cylinder to be burned and then exhausted. (This is accomplished by the use of very precisely located ports in the sides of the cylinder that are opened and closed by the piston moving within the cylinder) The piston, in it's downward stroke, compresses the fuel/air mixture in the crankcase until it (the piston) passes and opens the transfer port, allowing the compressed air/fuel to transfer into the cylinder where it is burned and then exhausted.

So, unlike a 4 stroke, using starting ether will result in there being a highly explosive mixture in the crankcase that any tiny spark can set off, and since the crankcase is not built like a cylinder to withstand the forces of that explosion the result is usually a hole in the side of the engine crankcase.

You can get a better idea from watching this video: http://science.howstuffworks.com/tra...wo-stroke2.htm

Hope this helps explain things.
