ok i had a carb knockin about so i took few pictures to help you.#
1st remove your carb
then remove the bottom four screws to take the bowl off
after that remove the 2 GOLD looking screws, you may need a pair of pliers for the bigger 1.
These are called jets and will look like this
these will need cleanin so you can see through all the little holes, use a tiny pin or somethin like it.
To stop fuel comin out the bottom constantly you will need to set the float, all this means is bendin this flap slightly down
You may have to take the bowl off & set the float a few times to get it right, trial & error!
Good luck & welcome!!
