    Choke doesent seem to help start it. Saturday I forgot to open the air vent on the gas tank, the motor started fine all day. When I was getting ready to go out Sunday I noticed that the vent wasn’t open ( plastic gas tank nearly flat) I opened the vent on the tank, and my starting (after setting)troubles returned. That’s why I thought maybe there was a check valve or something. This may seem like a minor thing but this is a pontoon boat and its difficult to reach the primer bulb. Thanks for your help Jim
