Don't laugh but.....don't forget to remove the exhaust plug!!! i bet you wouldn't be the last person to forget to remove the tail plug.

FWIW, I forgot about one of my intake plugs prior to start up and during run up quickly realized where it had gone while attempting to set max rpm. LOL nothing funnier than watching your wife just shake her head and walk away muttering something that rhymes with idiot as you reach for the extinguisher and manuel fuel shut off valve.

c'est la vie
