As already stated ...don't use it, If you feel you need to use starting fluid then something isn't correct with the engine/carb/.fuel set-up.
If the engine does not have a manual or automatic choke and you can see/touch the carb air input then you can plug it with your finger or a small ball on a stick while rotating the engine with the throttle open. When your finger gets wet the engine is primed.
If you can't get to the carb easily then you can get a small squeeze can or bottle with a long tip and fill it with some gas/oil mix. Drill a hole in the cowl where you can insert the tip in and squeeze some gas into the carb throat.
After priming the engine once or twice, it should fire-up and run. If not then again, there are other issues to deal with.
