If so, we will know it is not timing, but fuel. I have had cases where when I did the above, it fired and created enough engine vacuum to pull in fuel through a somewhat plugged carb and would run, albeit badly. I don't say to use starting fluid much, but in this case it can be a quick tool for diagnosis.
I agree... it can be used just for testing without any ill effects.
If you understand how the oil pump works, you will understand why this is not a problem.
Under normal conditions, when you start your engine, it is going to take a few seconds before the oil from the pump starts mixing with the fuel/air charge coming from the carb.
Where the Yamaha Enduro is still a current model...

Dave - you bring up a good point: starting fluid lacks lubrication, but also Either/starting fluid will cut the oil (Good at cleaning oil stains). the cylinder walls are lubricated by engine oil and spraying starting fluid to start it (repeatedly) is bad on the engine as the rings will wear out quicker. When the engine will only start with ether, due to rings wearing out and losing compression, it is known as an "ether dependent engine" . This most commonly occurs on diesel engines. I personally don't mind doing a light shot once just to see if it fires. The military loves starting fluid, some of our vehicles will auto-inject it when the temperature's gets cold enough. Glow plugs + Ether at the same time is a bad deal

I'm looking forward to getting it so I can check/change the points on this bike. Hopefully get some fire going so I can get it running.

Being a burned out geezer that can't remember nothing inspires me to great ideas like that.
