Sorry to post again, but have recieved no info on this problem. Put new thermostat in, motor had none in it. Cork gasket that fits behind thermostat is so thick that thermostat sticks out past the housing making it difficult to see how cover and gasket can go back on. Do i force it on and compress the cork or can I leave it out altogether? Don't want to mess up motor , finall y got it running like a dream and fish are biting. Thanks
