    when my engine is warm i'll stop at a store for something shut my engine of for 10-15 minutes. when i get back in the car i go to start it and i have to crank it over for 30+ seconds before it will fire does anyone know why this happens and what i can do to fix it? i drive a 73 scamp with a 225 slant six with an automatic tranny.

    thanks

    I would guess the carb is leaking gas into the intake manifold creating a flooding situation. When you crank it long enough, it clears out the excess gas.

    my car did that before i put a new carb on it. it leaked horribly. HORRIBLY. dont burn up your starter cranking it for that long, i know i did. put the pedal to the floor before you start cranking it, dont pat it (accelerator pump will flood it even worse if you do), the open butterfly(ies) will allow enough air in to get the gas out quicker.

    I had that problem on my 68 mustang a few years ago.

    tried a carb change....no good....tried tuning...no good.....plugs....no good....

    I put in a pertronix and haven't had a problem since

    BUT this was on a ford
