I do alot of racing but I am just wondring if it is time to get a new motor
Sounds like a potential air leak. Make sure there are no air leaks. Also ensure that you are priming the engine prior to start.
There is a video on youtube somewhere on how to check for air leaks. check for air leaks, return the needles to factory settings, then retune.
The S7 is a great little engine that lasts a long time with the proper care. It is by far one of my favorite engines with tons of controllable power and easy to tune.
