pocket dirt bike dramas

hey guys n girls

i recently bought 2 pocket bikes off ebay. they are the little dirt bike ones and are pretty good quality compaired to some others.

however my bike has never been quite the same as the other bike.

my bike leaks fuel 24/7 and doesnt reach full rpms, and when it gets close it jerks violently as the engine stutters.

the other bike however is prefect, very fast, picks up revs instantly, pulls very cleanly and doesnt leak a thing and revs alot higher than mine! the other bike also has much higher compression (harder to pull the pullstart and turn engine)

ive had my carby apart lots and adjusted the float time and time again, it would stop leaking until i rode the bike for about 2 mins, then leak all over again.

the sputtering i gatherd was lack of proper fuel flow into the bowl so i took the carb apart and made all the fuel delivery holes larger and smoother, then thouroughly cleaned the carb to revome all debris. and replaced all fuel lines with larger diameter clear hose.

the carb still leaks but now when i accelerate full it just bogs and turns off, yet again not getting anywhere near full rpm.i can see fuel in the lines, so it isnt running out. but when i try to drain the bowl hardly any comes out. this is highly confusing as the overflow can only overflow when the bowl is too full, but its hardly dripping out ? then if i drop the bike from a few inches it pours out.... and still leaks >

what gives ! these things are F-ing brand new! and ive done all i can to the carb and its still screwed

any help welcome

thanks.

Sounds like the float level is set too high on the one leaking!!
