What is the gap on the spark plug on a Brigg's stratton lawn mower Model#31P777 Type 0348E1?
Briggs and Stratton 30W for 4 cycle engines.
it takes 20w50 motor oil
Briggs and Stratton does contract anyone to build mowers. The mower manufacturers contract Briggs and Stratton to build their engines (or whatever engine is on the unit). That is why you can have a Briggs and Stratton on most any type of mower. Same is true for Kohler, Tecumseh, etc. Not to say that the engine manufacturers do not build their own type of outdoor power tool but as the question states "snapper mower". Also keep in mind that if you have a snapper mower with a Briggs and Stratton engine and you need warranty work on the engine you need to go to an Authorized Briggs repair facility where as if you have a mower warranty then you need to go to an authorized repair facility for the mower manufacturer.
Depends on what type of engine it has. If it is a Briggs and Stratton or Tecumseh, then use 30 weight oil. If its honda, use 10w30
take the old plug to a mower parts store & tell them you need a matching one for a push mower
official site for Briggs and Stratton Spark Plugs is: http://www.briggsandstratton.com/maint_repair/routine_maintenance/choosing_spark_plugs/ The proper spark plug will depend on the type of 6.5 HP motor that you have. Briggs and Stratton made several different ones and the best way to get the proper plug will be to call an authorized Briggs and Stratton repair shop with the mower make and model numbers.
If it is a Briggs engine it takes SAE30. If it is a Kohler engine it takes 10W-30.
Type your answer here... It backfires because it is a Briggs and Stratton - replace it with a Honda or Kholer.
regular 87 unleaded gas from any gas station. if it is a 4cycle then you will not have to mix gas and oil, only 2 cycle engines require mixing the oil and gas. (this is the same for edgers, weed whacker (weed eaters) any kind of gas powered lawn equipment.
If that is a cast iron engine its 5 horse, look up Smiths small engines in Google that's were I get all my old parts.AnswerI used to have this really old snapper rider that i had to reguild the engine on and I found parts through the local lawn mower shops and through online lawn mower parts sites. Hope this helps you. Call the Briggs and Stratton tech support line on www.briggsandstratton.com. You might even end up talking to me!
