Hello everyone, I have a Briggs and Stratton 21B807 carburetor that I have taken apart from my Murray select riding mower, that I bought new back in 2004, gave it a cleaning, replaced a gasket and an o ring but I need to take it apart once again because I think I put a wrong o ring on, so I purchased a complete overhaul kit. So to make a long story short, I've been searching online for some type of legible diagram that I can actually read and see, even went to the Briggs and Stratton site, but there downloads don't tell me much, still have the old user manuals and their not great for repairs especially when it comes to the engine, would anyone have any specific schematics that I need ? Any help would be appreciated, thank you very much
