    VRO question J150STLESB

    After dealing with this Carb issue for several days, I decided to start testing my fuel lines for pressurization.

    Everything checked out good until I disconnected the vro line from the fuel tree. With my thumb over the line I can build pressure but it will not hold. I can hear “farting” for lack of a better term in the vro pump after enough pressure has been built. Would assume this means the diaghram is bad.

    I can only assume that the fuel is back pressuring into the vacuum line on the bottom cylinder and flooding the motor. Or is this issue causing the carbs to flood the motor?

    Thanks for everyone who has commented on previous threads help.
