inxs360

I have a 1977 xs 360 that wont start. When i go to kick it the motor wont turn, but the kick starter will still push down. It wont jump either.

Ive got a 77 xs360 thats having trouble stayin running. It wants to start when cold first kick, but once i start driving it and pull the clutch in to down shift it shuts off. It will jump start up again when i dump the clutch but if i dont it wont start until i give it time to cool down. Idk what it is maybe it just needs a good tune up. Any ideas?
