As a start just open 3 turns from closed, You really nead to crank this with a 1/2 A starter, at least for the first runs remember the coxs and other small engines used a spring to turn the engine over it just hooked on the prop and you wind it backwards then released it, you cannot hand flip an engine that quick and most likely the spring gave at least 20 turns
as quick as an electric starter martin

the 07 is not a very powerful engine bit should do ok in a light sport or trainer

the AP hornet 09 at $50 is twin BB, good carb and bushed rod, I have several and as matter of fact converted to diesel, they turn a 8x5 wood zinger at 11400
regardless it\f stock glow or diesel conversion its a great engine
