I have a self propelled mower (model 12AE46JA009) with a 173CC OHV engine that will start ok but it takes about 30 seconds to rev to full operating rpms. After it's warm, it will start and operate normally. Any ideas what might be causing this?

That is the time it takes for the auto choke to reach full operation temperature and open fully.
IT is quite normal.

Agree with Berts. Normal warmup time for most motors is 30-60 seconds
