My mother in laws jd self propelled mower has a B&S 6.75hp engine. It starts ok, but runs low rpms. when the choke opens it starts running rough then shuts off. I can restart it and keep it running if I hold the choke closed, and can get the rpms up if I manually increase the throttle while holding the choke closed or mostly closed. Everything is supposed to be automatic, choke and throttle. Any thoughts on how to fix this problem?

Problem could be carb related, and needs cleaned, or could be governor spring issues, that got bumped and killed the rpm's or could be more serious.
