    Probably a silly question but would a faulty choke cause the carb to flood?

    I've never touched the choke before only the carb itself, usually just need to empty the carb and it starts again no probs and works ok for about 4-5 days.

    With the carb upside down and the float bowl removed blow down the fuel pipe and check that the needle valve cuts off the air just as the flot top becomes level with the gasket face. Between the floats there's a little tab that moves the needle valve and it may need to be bent upwards slightly so that the float closes the valve sooner.

    The other thing to check is that the choke isn't stuck and corroded. Remove the C-clip and pull the choke out vertically. Look inside where the choke was as it can get blocked with crud and that would prevent the choke from turning off, causing the engine to be fuel-rich and flood.

    Your problem is one out of these two possibilities, so you need to check both.

    If your finding it to hard to diagnose the problem, you can get a complete carb for £25 for that scoot

    Euroscooterparts but you are correct there £35 but that includes a new auto choke and they are a 10er on there own so pretty good value really

    Yeah well I restored it quite a bit. Resprayed everything replaced tubes, wires etc. Didn't touch the engine as when i replaced the fuel and oil started and ran first time no problems! The problem with the carb has only started last couple of weeks.

    Well took it apart there and did the tests!

    The float works perfectly but the choke (going by the test that gilburton i think put a lonk too) isn't moving as much as the diagram. There is a little space at the top. So could either get a manual choke or get a new auto choke.

    Which is the best?

    Just get the Manuel one the auto ones are progressive and a bit ott for a little 50cc the Manuel one is more than officiant, tbh you don't even need to use it. my bike starts first kick you may just need it in the winter but even then it's not really nessersry I had a Yamaha slider 10 years ago for about 3 years and it had a Manuel choke and I never needed to use it once

    If it's not extending as far as it should that means you will be getting too much fuel as when warm it extends and closes off the extra fuel drilling.
    There are 2 types of manual choke. One is the small flick on/off which means if it's not fully warm when you ride away you'll need to stop and flick it off.
    The other is the same thing but it has a cable/knob attached so you can site it somewhere handy eg front of seat.
    Some kits come with the option of both.

    Ok, manual choke it is then! :p

    Is there a certain one for my carb or just a general one?

    Go for the cabled manual choke, as the flick lever type can be awkward to get at behind the plastic panels.

    If you have the the horse shoe type fitting on the choke with two screws then the one I put a picture of earlier will fit
