AN MD80 ON ACCELERATING FOR TKOF; THE R ENG WOULD NOT COME OFF OF IDLE. SHUTDOWN ENG AND RESTARTED; ACCELERATION NORMAL.

Narrative

WHILE TAXIING OUT FOR DEP AT ZZZ; THE R ENG WAS STARTED WITH ALL NORMAL INDICATIONS. WE WERE CLRED ON THE RWY FOR TKOF. WHILE ACCELERATING THE ENG TO TAXI ON THE RWY; THE R ENG DID NOT ACCELERATE OFF OF IDLE. THERE WAS ANOTHER ACFT ON FINAL SO WE CLRED THE RWY TO TROUBLESHOOT THE PROB. BASED ON THE PAST EXPERIENCE OF THE MD80; I SHUT THE ENG DOWN AND RESTARTED IT. THE START WAS AGAIN NORMAL AND IT NOW ACCELERATED NORMALLY. TKOF WAS MADE WITH NO FURTHER PROBS. UPON ARRIVING AT ZZZ1; I CALLED MAINT CTLR AND TOLD THEM WHAT I HAD DONE. THEY TOLD ME TO WRITE IT UP SO THAT THEY WOULD HAVE DOCUMENTATION AND ZZZ1 MAINT WOULD TAKE CARE OF IT IF ANYTHING FURTHER WAS NEEDED. IN RETROSPECT; I WOULD HAVE CALLED MAINT AFTER I CLRED THE RWY AND LET THEM MAKE THE DECISIONS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THE PRATT AND WHITNEY JT8D-219 ENG HAS HAD THE BLEED VALVE STICKING OPEN PROB LONG ENOUGH FOR MOST CREW TO UNDERSTAND THE PROC FOR RECOVERY. SHUTDOWN AND RESTART!
