Make sure throttle slack about 1/8" slack or can die also! Master cylinder piston and seal kit available,but need installation tool to keep from damaging seal. IF talking about leaking around top bowl as many I've seen do,remove cap,clean corrosion/dried fluid around grooves in top bowl,keep fluid level slightly LOWER than full mark on inside bowl.

if i never messed with the screw do you think i should start now or what. i just pulled the spark plug and its black and wet what does that mean.

 

if the plug is black and wet its running too rich (too much fuel entering cylinder). maybe your airfilter is dirty and not letting enough air through?

 

i was let it run with air filter off i ahve to keep it ideld aliitle or it will die.

 

try adjusting the screw that will lean out the fuel mixture, because if the plugs black and wet you have too much fuel

 

Sounds like pilot jet has some blockage to me.
