    if the engine is not running, when you press the pedal, the accel pump will squirt fuel in. you would need to pump a fair few tims before flooding it.

    depends if it is in water or not?

    i think you should google for the answer to your last question.... it's not really "tech and conversions" more like Autoshop 101

    If you flood it, open the throttle fully, and crank the engine till it starts spluttering, then nurse it to life. Best thing to do is not to pump fuel to get it started, rather have it tuned properly, perhaps rebuild the carb and all.

    i dont entirely understand wat ur asking, but ill have a shot anyway...

    if u pump the accelerator before cranking the motor over, ur carby will let fuel squirt into the engine, wen u go to crank it, ulll get lots of smoke, and it will splutter. that will go away shortly after, and ull be sweet. well most times anyway.

    like oldcorollas said, it will take a few pumps to flood it to the point that it wont start, but if thats the case then u can do wat o man said, that should clear the unburnt fuel...

    if thats how u gotta start ur car all the time, then get ur carby tuned/rebuilt. depending on how bad it is...
    i have to give my 4ac a lil squirt of throttle every morning, but once warm its usually sweet... so i dont bother wif tuning it..

    I have to do the same with mine, only way to get it to start almost first time is to keep pumping while starting it. Otherwise it will just try to turn over for like 10sec before starting and it will be really low revs. Did flood it once but that wasnt too bad, just was very very lumpy and a bit of smoke.

    I think u dont even need to turn on the ignition...just having it off and pumping the accelerator is enough to flood it...ull just have a bit of a hard time starting her...with abit of smoke on startup..but after that she should be fine...

    well is it cranking, coz if its cranking it wont be the batteries !!!
    if you are pumping it whilst tryin to start it, my guess fuel pump or something like that if it wont go at all !!

    could be a seized motor if its locking the wheels, unless you are on soft ground. Try it on a hard surface and in 3rd gear. Mind u, i started my uncles KA lazer on crusherdust in reverse when he had a flat battery and took my car to work. Was doing about 2kph when i started it

    clickclickclick when u turn the key is the battery
    what gear have you got it in?
    second is recomended to roll start
    but if my carbie playing up (i have rust in the bottom of my fuel tank and sometimes it will block filter or a jet) i just dump the clutch in first, from anywhere as high as 40. huge tyre squeel but it creates enough pull to dislodge the crap.

    so yer, first or second on a grippy surface should so the trick if the battery is still fuggored

    is 'flooding' only possible if u have a mechanical fuel pump or can u do the same with an electric fuel pump with a carbie?

    no. not at all.
    when a greater fuel supply is required on a carburetted engine a high volume low pressure pump is used.
    often find it with tuned 5k's or 7k's
