1986 Honda ATC 250r - Leaking Gas

[predrider305]

Just bought an 86 atc250r and it leaks gas from the carb when its off and the petcock is turned to on or reserve. Why?

[oxidized_black]

probably the seals are gone in the petcock ...

Check the float in your carb. It's out of adjustment, or has a hole in it> Bruce

if its leaking gas even when the fuel valve is turned off then the valve is bad and needs replaced or repaired ... and the carb also needs cleaned and adjusted or rebuilt with a new float and needle valve .. i have had sever of the honda 250's and they tend to leak fuel from the carbs alot from dirt and bad floats ... as the original float was brass with lead seal.. that have a tendency to leak fuen inside them and cause the needel valve to open and over flow the carb ...
