Clutch Issues

[Jsut4fun@aol.com]

If I haven't driven my 76 TR6 in a while (storage, etc) the  clutch pedal has 
no pressure behind it and will go to the floor.  If I run  it for a while it 
seems to firm up a bit and will eventually disengage the  clutch and allow you 
to put the car in gear.  Once I get it back on the  road for a while 
everything seems normal.  In the summer when I drive  the car more often it is 
not a 
big issue, but it is still a concern.  Can  anyone suggest what is happening?
Thanks,
Ken
