IF your master and slave cylinders are BOTH below the clutch fluid reservoir, you can do a gravity bleed.

Basically, all you do is remove the lid from the fluid reservoir, crawl under the car and open the slave bleeder valve and let the fluid drip into a catch can. Stay close and refill the reservoir as it gets low. You don't want it to run completely dry or you could introduce air into the master cylinder.
Once you have filled up the reservoir a couple of times, all the old fluid will have been cycled out. Tighten the bleeder valve, top off the reservoir and go for a drive.

This is how I have bled my SPF tons of times. Very simple.

Hopefully this cures the problem. It's by far the easiest thing to check. Sounds like a little moisture in the line.
