as i am going along, i have to give it more and more throtle to keep it at high rev's. BUT as i do so, petrol starts poring out of the "TOP" of the carb. Once this happens, Every time i start my moped, petrol starts coming out of the top of the carb. i have taken off the bottom of the carb and can not see any problems with the main jet's "size 60", slow running jet "32".

Weird thing is, once i take the bottom of the carb off then put it back together.... Its ok for a bit... then i happens AGAIN!

Please can someone help :)

the problem is not with the jets but with the float or float needle or needle seat allowing the fuel to keep flowing in after it has reached its full floatbowl limit.
