    Has the impeller been changed to a different one? or you may a bad exhaust baffle and its restricting the exhaust flow.

          Yes, and they can melt causing exhaust back -up choking out the engine.

              The flywheel key may have broke and is throwing off the timing or has pushed out when you replaced the stater. Check the key.

                  Yes but check the key, if you didn't tighten the flywheel properly it could sheer the key.

                    Also check the water flow tube that goes through the computer, it keeps it cool and if it over heats it will limit rpms
