Pull spark plug, squirt about 2cc of gasoline in the hole, put plug in, apply choke, closed to 1/8th throtte, and pull. Should fire right up. If it does that it's capable of being started by cord. Now you just modify your procedure next time. Don't pull the plug just apply choke, throttle, and pull. But don't leave the choke on for more than two pulls otherwise it may have pulled in two nice slugs of fuel and flood. If it fires at any point it should run. Don't pull more than two times with switch off and choke on. Switch on, choke on, pull no more than twice. Choke off.
