Alright guys, so I recently bought a Southbend TZR clutch and flywheel with ZSpeed's CSC. I have 2 problems.

After the clutch was installed it felt good. Engagement was at the top (like stock) and I had about 1'' or less of pedal play. After I took it out for a drive everything seemed ok pedal wise. After about 5-6 miles of driving, pedal play increased to almost half of the total pedal swing (60% play 40% engagement) and engagement point was no longer at the top.

Since then I have tried adjusting the pedal inside the cabin, gravity bleeding for about 20min, then regular bleeding for about 30min pumping about 20 times between valve openings. After I am done pedal feels ok but the same thing happens after I drive it for a a few minutes.

The other problem I have is that regardless of the pedal feel, it is hard getting into any gear after putting the car in neutral. This only happens with the engine on...
I start the car in the morning, force it into 1st and drive around, all gears engage ok. I get to a red light, put in neutral, release clutch... when I try to go into 1st it doesn't want to go, I have to force it in again. It does the same thing with any gear I try from neutral. Once I push hard on it and get it into gear, I can row through all gears again with no problem..

I think issue number 1 is air in the system but I don't know how that could be since I've bled the sh1t out of it. Issue number 2 sounds like the clutch is sticking or CSC is not pushing all the way in.

Advise?
