K1000 ISO settings

The film speed selecter no longer moves on my K1000, its set at 100. I want to start using the camera a lot more and want to repair this feature, has anyone done it, have any recommendations? With it being christmas, i can't really afford to send it away for costly repairs.

The ISO setting only calibrates the meter. If it is stuck at 100 and you wish to use 400 ISO film, meter with 100, then stop down 2 stops-either increase shutter speed from say, 125 to 500, or change aperture from say, 16 to 8. After a while you'll stop worrying about the meter!!

..perhaps 8 to 16?

Yeah, that's what I meant!!

Easier to do than to remember without a camera in hand, I guess.
