did you install a new throwout bearing?? did you put a little antiseaze on the throwout bearing sleave ??
not sure why you dont have good pedal unless you have some air in the system, get someone to hold your clutch down then use a 10mm wrench to crack the bleeder on the slave cylinder, dont let them lift the pedal until you have tightened the bleeder or it will suck the same air back in, do this a couple times or untill you get a solid stream of fluid and your pedal should be firm
if you cant find me here you can email me directly, email is on my Marlin profile
