Narrative:

On takeoff #2 engine EPR gauge only came up to 1.75 (should have read 1.95). All other instruments appeared normal for full power but I elected to abort the takeoff and check the engines further. Aborted at 90 KTS. Used long rollout and minimum brakes (13,000' runway) and pulled off and did engine full power runup. Now everything worked properly. Took off and everything was normal. All indications were normal for remainder of flight. There being no maintenance available at this station and no recurrence of problem, I elected to continue flight. This may be the start of a new generation of problems with CRT type engine instruments. I hope not.

Title: ACR MLG TKOF ABORT DUE LOW EPR READING.

Narrative: ON TKOF #2 ENGINE EPR GAUGE ONLY CAME UP TO 1.75 (SHOULD HAVE READ 1.95). ALL OTHER INSTRUMENTS APPEARED NORMAL FOR FULL POWER BUT I ELECTED TO ABORT THE TKOF AND CHECK THE ENGINES FURTHER. ABORTED AT 90 KTS. USED LONG ROLLOUT AND MINIMUM BRAKES (13,000' RWY) AND PULLED OFF AND DID ENGINE FULL POWER RUNUP. NOW EVERYTHING WORKED PROPERLY. TOOK OFF AND EVERYTHING WAS NORMAL. ALL INDICATIONS WERE NORMAL FOR REMAINDER OF FLT. THERE BEING NO MAINT AVAILABLE AT THIS STATION AND NO RECURRENCE OF PROBLEM, I ELECTED TO CONTINUE FLT. THIS MAY BE THE START OF A NEW GENERATION OF PROBLEMS WITH CRT TYPE ENGINE INSTRUMENTS. I HOPE NOT.
