Briggs and Stratton 500

Posted by hersheyhome (My Page) on

My Neighbor has a Briggs 500 on a bolens push mower (low end Lowes mower). The mower is about a year old and she overfilled the oil by about 6 oz. I drained off the excess oil and cleaned the plug and air filter. The mower will still not idle smooth. It doesn't blow any smoke from the exhaust anymore but idles up and down as it runs. Any suggestions?

Is the gas fresh or left over from last year? Try some fresh fuel with some Seafoam in it. You may need to clean out the carb if the Seafoam treatment doesn't help.

i put fresh fuel in the tank. it started running really poorly on the last use of last year.

RE: Briggs and Stratton 500

Try replacing the plug and air filter. One or both may have become fouled.

If you put fresh gas in the tank but it was half full of last years gas, you may still have a problem with stale gas.

RE: Briggs and Stratton 500

Putting new fuel in the tank doesn't get the old stale gas out of the carb if it sat all winter. Try spraying some freah gas into the carb throat and see if it will run for a few revolutions.
