Sound like you not fully releasing; start by bleeding. You should be able to push car with engine off, in gear and clutch depressed.

If not, then look into adjusting some of free play out of the TOB. You always want just a bit of play so the TO does'nt drag and always be loaded and spinning with the clutch.
You might want to attempt to measure the TOB throw to see if it's in specs. If the throw is low, you can rectify by larger dia MC
