To start a two stroke by hand I put my finger over the carb then turn it to pull the fuel up. If you do this with the heater on it, the engine will kick back(while you have a good grip on the prop). when the mixture is right. When you feel this kick, get your chicken stick and flip it. The starting fluid will work, but it is also something to have to keep track of. I forget enough things already. Just for fun I sometimes start my four strokes by flipping the prop backwards. If I get a good prime, the engine will backfire when flipped. Since I am flipping it in reverse, the backfire starts the motor!! If it doesn't start right away or burns the prime out, I go ahead and use the electric persuader. :-) One fellow in our club starts his 4S by spinning the spinner backwards by hand. Just a little flip and it starts idling.
