Why Briggs & Stratton MS-0750 will not start?
- A
  Aaron GomezAug 8, 2025
  If your Briggs & Stratton Engine won't start, it could be due to several reasons: * Safety equipment installed by the Original Equipment Manufacturer (OEM) might not be functioning correctly, preventing the engine from cranking. Ensure this equipment is working properly and isn't hindering the engine. * Low battery voltage (below 11.7 volts). Check the battery voltage from the positive terminal to the solenoid terminal; it should not be below 11.7 volts. * A defective starter motor. If the starter does not turn over, the starter motor is likely defective and needs replacement.

How to troubleshoot hard starting of Briggs & Stratton MS-0750 Engine?
- J
  Jacob BurnsAug 15, 2025
  If your Briggs & Stratton Engine is hard to start, check the following: * Ensure the oil level is correct, as the engine is equipped with a 'Low Oil Pressure Sensor' and won't start if the oil level is too low. * Make sure the drive unit is disengaged. A loose drive belt can cause a backlash effect, counteracting the engine's cranking effort.
