My 250 used to never leak gas. I could leave the petcock on indefinately and it would not leak.
Now, however, it leaks from the float bowl drain tube if I leave the petcock on. I'm forgetful and I hate to waste gasoline.
After reading the last few posts concerning this issue I have deduced that...
No. 1..... I should remove the float bowl and check/clean the valve and valve seats.
No. 2..... Check/adjust the float height.
If everything is OK I should be able to leave the petcock "on" and have no leaking problems.....correct?
