Hello, Can you adjust the gap setting without dismantling the razor? My #1 is more like a #9 and my #9 is an 18.
Sounds like the razor was "overclocked". Put it on setting one and then use a paperclip or something similar to depress the red spring above the adjuster knob and them rotate the adjuster to the left to setting 9.
Welcome to TSD @Ambrose21! Glad you signed up, and I personally approve of a Fat Boy on number nine. Haven't tried one at 18 yet. I hope Andrew @Linuxguile answered your question. If you have a few moments, visit The Welcome Center and introduce yourself.
