Hello, my name is Hank, and I am going to assist you with this.
Yes, that genset should run a 15A compressor.
That genset is rated for 23A running, 33A starting.
Your 15A compressor will have a start of around 30A.
If the engine is being under powered, it is due to a bad carburetor not letting enough gas through for the engine to develop full horsepower.
Replace the carburetor.
