B&S 44M777 Intek engine, 3 years old, changed to 10-30 Weight oil, new plugs, new air filter, 200 hours on engine.  I have good connections at battery, 12.66 volts at battery.  Starts immediately when jumped with battery charger with jump-start cycle.  
Seems to turn over slightly slow, turns over a little faster when connected to battery charger using jump feature...then it starts.
What is the likely cause of the slow starting? Light oil, new plugs, new air filter, what am I missing?
