    ‘06 510SMR leaking gas into cylinder! I tried to start and it was hydro (gasoline) locked! Pulled plug and ran starter and gas sprayed out. Lol! I dumped oil and half a tank of gas was in there? Wtf? What do you guys think? Stuck float is my first guess? My head hurts from huffin’ gas fumes all day!

    I never leave the gas tap on unless I am on a ride, and I drain my carb after every ride on my old TE 450. So, I never have that problem.

    I never had that problem either until yesterday. And I do keep petcock off when not riding. It still does not fix underlying issue. Gas should not be leaking into the cylinder!

    Replace float needle and seat. The brass seat has an O-ring that is a common failure point as well.
