Always check your gaps - these mowers are finicky about the compression - intake vs exhaust not exact, too much compression, which many diagnose as the battery. I have had more than one shop throw a new battery at this problem, with no resolution (maybe one or two starts - all depending on the position of the piston during the initial crank). Symptoms will tell you there is not enough amps - but the compression is too high. You can try to turn the flywheel by hand and you should be able to "feel" that the compression is too high. Very easy fix with feeler guage.
