If you are still available. I am sending you a message and I am not happy at all . I received a YS 120 four stroke and I listened to your direction on how to run the fuel lines for my motor. Big mistake. You stated putting the check valve in so air could NOT be blown into the tank. I listened to this and I ruined my beloved ys motor. You have no idea what you are doing. I ran my motor and the fuel tank emptied into my engine which caused it to run backwards ruining the piston sleeve. Now my awesome motor with much compression is now ruined. I should call you every name in the book but the damage is done. Don't give people your limited knowledge because it will cause damage to equipment. Damn I was a fool to follow your direction.
