yeh checked that a while ago.Will check it again but it should be all right

What is your intake configuration? Do the three carbs feed a common plenum with lots of mixing, or is it more stratified flow? Also, is your center carb the one with idle/secondary function with the outers only having secondary like a "traditional" 3 carb setup? Teenagers like to "tune" - any chance the back carb got "tuned shut" at idle, making it run lean in back at WOT (probably at WOT a lot with a young driver...)?

No the mechanic balanced them with a flow meter and it's 1 carby to 2 intake ports and then there's a straight runner that joins all three carby connections together but the power booster is connected to the rear carby ( where cylinders 6 & 6 are )
