im using pull start. Usually to prime the engine, I pull out the backpressure hose to the fuel tank and blow into it lightly until the fuel reaches the carb. Then, i stick it back in, stick on my ignitor, count to 2 adn start to pull. Every once in awhile, il pull the servo rod connected to teh throttle rapidly about 3 times and keep pullin. Usually itll sputter, then ill do it again and itll fire up shortly after. This time, i tried the finger over stinger thing and it primed it, or so i thought. I am seriously considering a starter box whichll run my about 110 clams, but i think itll be well worth it. maybe ill try that and see if my starting probs go away. Also, im gunna get a rechargable ignitor instead of my d cell thing
