Looking for features that are available with a specific engine
First time post, new member. I love your site! I was wondering if there was a list of engine model numbers for Briggs and Stratton that can tell you what features are available. I have a 121S07-0020 I think (875 Professional Series OHV Electric Start Only with a heavy flywheel). I was wondering if there was a similar engine with the pressurized lubrication (sump) as opposed to the slinger (splash) lube. I have this engine mounted on a push mower and it runs fine, I just thought it would be nice to have the oil filtered, as oil lifetime seems to be significantly longer when the oil is filtered. Thanks, and keep up the good work!
