the small petrol pipe goes on the fat nozel m8 as you look at were the air filter was down the carb the pipe goes on the 3rd 1 to your right.hope this helps.if the petrol pipe is in the midel of carb it will flood you case and you will need to remove spark plug and kick it till it all flows out

petrol does get into the crancase anyway as a vapour then its tranferred up through the transfer ports in the barrel as the piston comes down the bore and compresses the fuel /air mixture in the crankcase.if you put fuel in the plug hole even if it did run past ther rings which it would if you left it for a minute or two anyway it would only go into the crankcase and get transferred back up again and chucked out the exhaust port.if its flooded then open the throttle wide open and kick it fast and hard.it may foul the plug but you will just need to clean it with brake cleaner or some fresh fuel and put it back in.if its flooding then like m says the vaccum taps diapragm is not working properly and letting the fuel into the carb all the time saying that the float needle should stop it flooding really if its working right.the float may be cracked and full of fuel have a look at it closeley and shake it.

little more info please, cut out whilst driving, ran out of oil? etc... the crankcase has no other reason to fill up with fuel unless one of 2 things are happening!either the float in the carb is stuck or your fuel tap is goosed! the fuel tap only works under crankcase pressure . 2 pipes come off the fuel tap, top fuel to carb, bottom is vac pressure, take top one off whilst not running and if you have fuel still coming out its goosed, if not then its highley likely you should get a compression check done, should be around 120 psi to run properly, but can run off as low as 90 psi, chances are you have a compression fault because if it doesnt run when you introduce fuel direct then its passing the rings and therefore fooked

why do you think this?
Have you checked for spark?
