Default Can't get fluid to flow out of bottom of master cylinder

So i got my 383 fired up last night, sounds great, idles well.

However my clutch pedal is just flopping around, I disconnected the slave and pumped the clutch and tried to get the fluid to go down through the master, no luck, so I disconnected the line going into the master cylinder and I still can't get fluid to go through the master cylinder and out of the bottom hole that the slave cylinder connects to.

not sure what to do.

Have someone push the clutch to the floor, and hold it there. Put your finger tightly over the hole where the line goes, then have them let off the pedal. Repeat as necessary.

sounds weird, have you tried bleeding the system. and don't press on the clutch when doing so. if you don't know how to bleed it hit me up i can help out. i just swapped out my master cylinder and bled the system.

so my buddy was over and recommended trying to blow down in the reservoir with my compressor, a bunch of white smoke came out the other end and some fluid started to pour out, very little though. Then some white gunk started coming out.

seems like it is backed up, any way to clean it out or some chemical to use to open it up? or should I just keep using the compressor to blow in it?

how fast should the brake fluid be coming out the bottom end of the master cylinder, just a little at a time or pretty much free flowing?

with no obstruction the fluid should run out. try bleeding the system to see if you do have a obstruction.

I pulled the master, is there supposed to be any force against the plunger when you push on it? Barely any fluid goes through the master even with just the reservoir connected, heading to kragen to pick up a replacement. Let me know if I should try something else, thanks.

The master cylinder was bad. Got one at kragen for 50, seems to be working fine. Buy of course I now have another problem which I will post in another thread. Thanks for the help.
