i spent the last few hours making sure all my valves open and close fully. they do but i have one issue. the flapper on the main exhaust doesn't close fully when wide open. there is some slight play in it( as in hangs down a little) no matter how much i take it apart and adjust it, i cant get it to close fully one its own. i can physically pull it and get it to close. it just seems like it's hanging up or something. is this normal or is there an issue?
