Okay, so here is the situation as best I can describe it.

These potentiometers are very inadequate.

The one marked intensity is basically an off/on switch kicking in around 6 or seven. The one for speed is way too fast however.

I figure I need to change the value of these pots, but should I increase them or decrease them? Or go one way for less speed and the other way for more intensity?

Any help would greatly be appreciated.

so...do you know which size pots I need? I'm clear on the values now, but do I need a 3/8" bushing or an 8 mm bushing?
