iskate2 may not have even flooded his engine, there is usually one or two "sweet spots" where the motor will completely lose compression if it sits
I've had it happen a few times, 10 of the ten second starting bursts seemed to always do it, also premixing may help alleviate this and leave a nice lubricate apex seal to hold the compression better

Zammm watchout on how many time you flood the car, after about 5 floods the plugs tend to get fouled badly, my FD wouldn't start on cold days till I changed out the plugs
