Have a 3016hst using it the other day getting garden ready was running fine went and put fuel in it and shut off, once done fueling went to start and acted like battery was dead, tested battery and it was on the weaker side so replaced with new, still the same thing maybe crank one or 2 revolutions then just stuck acting, took starter off and found it was on last leg as well, so bought a new starter tried to spin over once normal and then back to barely cranking at all install new cables as well. At a loss can a bad hydraulic pump be my issue acts like the starter is under a major load?
