Is the engine brake sticking on?

If its ambc you likly need to replace the triger tab inside the pump! BUT you can try backing the screw out till it works correctly! loosen the jam nuts on the out side and back the screw out 2 or three turns rev the engine and let it off it the brake works but shuts down after half the rpm range then your half way there. turn the screw in 1/4 at a time till if at top rpm the brake dosent come on! Snap the throtle at the top rpms Quickly and hold it at top rpm if the brake trys to come on ,back the screw out sum more! If it dosent come on turn the screw in till it comes on!Ya hve to mess with it a bit to get it right if you cant acheave a desent set where the brake comes on then shuts off at aprox 1000 rpm you likly need to replace the triger tab!the Rob bosch pump is the exsact oposite!
