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
 
1, are you talking about the NIKKI carb,

2, is the part number 692158 seal o-ring intake manifold (the thicker one)

3 is it part number 691917 seal o-ring intake elbow

4 is it part number 697123 seal o-ring intake elbow
 
Thank you guys for getting back to me so quickly, just to clarify I have the Murray Select 405000x8c with the Briggs and Stratton 21b807 engine with the Nikki carburetor I'm gonna post back with some pics and make sure which o-rings I touched with the numbers you gave me
 
Hi again, it's the bowl gasket and inlet o ring,
I'm trying to upload pictures but I'm having a Problem, but the numbers on the carb are 699475,G02525,4209C

I think its 698781, it's my first time taking a carb apart and I want to make sure I'm putting them back the right way, I don't think it's the numbers you had mentioned, thanks

SF1 I will try to see what carb you have...........

Do you have 1 bowl nut on the bottom or 2 phillips screws to take the bowl off........ Did you have a noodle gasket inside the carb or a single O ring type gasket for the bowl ???

The noddle gasket is a Nikki carb and the O ring type is the Walbro carb.....

Let us know Mon Ami ~!~!
