When I take the gas tank out ( with the petcock closed ) and let the gas that is in the hose drain out till nothing comes out any more, then set it down to work on a crab problem I'm having, it ends up leaking more and more as it is sitting on the floor. So first that is a leak correct, meaning its not supposed to do that? Second and this is sort of off topic, but that could be filling up my carb bowls when sitting turned off right? Let me know what you think.
