My Murray tractor stalls when I release the clutch. I tried to adjust the clutch but that did not help. Any ideas.

You may need to check all of the safety switches starting with the seat. The switch may be telling the engine that no one is seated on the tractor so it kills the engine. There is a switch for the blade engagement and the cltch/ brake too. Flip up the seat and follow the two wires to the switch, use a continuity tester to see if it is open when not seated and closed when seated.

ballengerb1 you got it dude, sounds like the problem to me.
