Still Not starting after everything ive done

Okay i bought an aerox for 200 quid, which had broken reeds. i put a carb that i knew was working on, and made sure fuel is going through it. i put new reeds in the engine, and it started for about 10 seconds after loads of kicking. since then it hasnt started. apparently its got a 70cc kit. and the spark plug is quite hard to put in, as in hard i mean takes a bit of effort with the spanner. still no joy, apparently the spark plug in it, isnt a long enough reach one, would putting a longer reach plug in make it work? another thing ive noticed is that there is definetly a spark, and when i take the plug out there is alot of fuel vapours, more than ive ever seen coming out, can anyone tell me whats going on as im very confused, thanks for your time.

it sounds like your crankcase is flooded with fuel, leave the plug out for a couple of days and every now and then kick it over without the ignition on to try and blow some out. other than this tip the motor upside down to drain.

 

try a br9es thats what was in my polini 70

 

check all wires are connected to the coil properly

 

Try starting it with throttle fully open.
