I have some friends and myself included, when you get ready to start and your priming your bulb, prime that sucker extra. You can hear gas through the cowling if you listen. My friends 200 Merc would crank and sputter for ever. I told him this trick and he thought I was crazy. After about 4 times of waiting at the ramp, the 5th trip I just went ahead and did it myself. That baby fired on the 2nd rpm, wherr-fire. He couldn't believe it, I told him it's a 2 stroke and they're almost impossible to flood and even if you do, you ain't gonna hurt nothing. So in short, pump that bulb and then pump it some more
