Re: 17.5 HP Briggs & Stratton Carburetor Adjustment
The model is 31C707
Type is 0603B2
Code is 090803ZA
The part number of the carburetor said it was obsolete, and no longer available. This one was the replacement recommended, and the engine Model & Type was listed as covered by the replacement part number.
It was originally a NIKKI carb, but when I tried to rebuild it I wasn't competent enough, and it didn't work. When I tried to re-assemble it, it wouldn't let fuel through to the engine, and I think I messed up the way the jet fit with the solenoid that shuts off gas when the ignition is turned off. Then I messed up a gasket that was not included in the rebuild kit, and that allowed gas to leak into the manifold. I gave up on the rebuild, and bought the new carb. The engine runs, but not at high speed
