Cool Where can I get a "real" carb for my B&S?

In the last three years I have purchased two push mowers with B&S 158cc engines. Both experience the same behavior. The automatic throttle governor drives me crazy! The engines constantly sound like they want to stall, then they speed up again.
Is there an improved spring kit that would help with this?
Or is there a carburetor with a real throttle control that will work with this engine?

Thanks in advance!

That surging is due to a carburetor restriction...trash or water in the carb.

The numbers you posted are only government related emissions identification not useful for us. You will see a model, a type and a code number stamped into the flywheel shroud that we'll need.

Your Diaphram is leaking...........

The words you never want to hear from your girl friend....but you will from your local small engin repair shop. If it like mine, The POS briggs plastic carb uses a diaphram to control fuel flow, not a needle.......that together with crude and these engines will never run as they did new. I replaced the diaphram and it lasted about 9 months...now the surge again!

Personaly I like the B&S with the plastic carb, carb setting on the tank, people buy them, the diaphgram dries out, they disguard them as junk, I pick them up and install $3.00 495770 diaphgram in about 15 minutes and have a mower that runs like or better than when bought new, for sale. A throttle control can be attached to the same carb, you just need to bend the tab up that stops the throttle clntrol from moving, it is bent down just bend it up out of the way. Have a good one.

Go to your local small engine shop and get diaphram kit #495770 or at Lowe's they have the kit at either 495770 or 583. Remove the air cleaner, remove the 2 fuel tank bolts, one 3/8, one 1/2, slowly slide the carb off the intake and crankcase breather tube, now tilt the carb/tank inward and down to diaengage the governor control arm, now remove the carb/tank. Remove the carb from the tank(5 screws), remove the screen and clean it, using a small screwdriver pry the main jet from the stem(on reassemble it takes some pressure to snap it back in place)spray all holes,cracks and crevases on the carb and tank using carb cleaner/brake parts cleaner(I use both, carb cleaner first and then brake parts to remove the carb cleaner residue), put the main jet in, put the screen on. Set the diaphgram on the tank, the gasket on the diaphgram, the carb on the casket(careful not to loose the diaphgram spring)align the diaphgram,gasket,carb holes and put in the screws, put the tank back on the mower per reverse of removal and your done. Have a good one. Geo
