Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Engine model number?
Will engine spin freely if you remove the spark plug?
Do you have a voltmeter to check the voltage when you turn key to start?
Was old battery same CCA rating? Did you clean the battery cable connections? If you find voltmeter, the battery voltage has to stay above 8 volts while cranking. If it does, and engine does not spin, the starter is bad.
If engine acts like it is hard to turn from initial contact, on single cylinder Briggs engines, the compression release may not be working.
You would want to replace it.
Best prices from amazon or Ebay.
You didn't give me engine model number!
Mower model does not show it
693551 should be right one.
If voltage drops below 8 volts, battery/cable problem.
Do you have compression gage? If over 100 psi, the compression release on the camshaft can be damaged! Not common on this engine, but more common on the newer Intek single cylinder Briggs engines!
Battery or cable is only reason voltage drops that low. Go back and check the cables, and a nee battery , fully charged should be 13 + volts
Has to be battery or cable problem. That is the only reasons the voltage will drop like that!
