was out on my bike over the weekend up charlton and war riding down near the via-duct, i was crossing the river when suddenly the front wheels slipped and the bike went under. i got the bike ticking over but as soon as u reved it a little it wud just stall eventually i got the revs up a lil and got it up in the carpark. i then finally got the bike reving as normal. i got the bike home and cleaned the carb out and flushed the tank out and i put the carb back together and now when i start the bike and leave it ticking over petrol starts pourin out off the over flow, now my bike (montesa cota 311) has 2 float and 1 is is 1/4 and the other is 5/8 and ive tried them both ways and it still put petrol out of the overflow and the floats slide up and down ok and the carb is clean any ideas plzz liam
