No you are not correct, it is a 4 stroke engine, suck, squeeze, bang, blow, so stroke 1 downwards, fills the cylinder with air/fuel mixture, upward stroke compresses, it is at this point it fires, the downward part of the next revolution is the power stroke, the upward the exhaust, then back on a 'filling' or suck stroke. So from that simple primer how many revs per ignition?
