12HP carb
« on: July 13, 2006, 02:48:09 pm »
I am rebuilding the carb. on a 12 hp briggs and am wondering, should I use the rubber seat for the float needle or not? The orig. carb didn't have one. What are the advantages and disadvantages of the soft seat?

Some had the seperate needle and seat some didn't Tends to be in the older ones and few and far between. If yours has the rubber tipped needle that is the way to go the others for the walbro are very hard to find. Many don't even know they exist.

Thanks for the info. I couldnt have used the soft seat anyway, but they do send them in the rebuild kit from prime line. does anyone know of any modifications that can be done ( in the home shop) that will make this carb. better on a racing mower?
