Mend Briggs & Stratton 8hp Gas Leaking Carb

Gas leaking from carb?

On my 8hp B&S i have gas leaking out of the carb, i rebuilt the carb with a kit.The kit came with gaskets and 2 adjustment needles and springs, for the float it gave me a very small rubber gasket and 2 needles or wieghts and a hinge. How do i know witch needle to put in and am i to put the rubber gasket in also? When i put in the larger needle with the gasket the float isn't level. When i put the carb back on and start it, it leaks. How can i fix this ? Thanks for any info.Dave

Dave,

You should have one needle with a rubber tip on it and one without. If your carb has a brass inlet seat(where the needle fits into) you will use the rubber tipped needle and no rubber seat. If your carb has a "drilled or milled" seat oftimes with no brass insert then you need to install the plain needle with the rubber seat. Always install the rubber seat with the little groove facing away from you or the needle. Make sure it is in flat by using a flat drill bit end just smaller than the inlet to push the seat flat into the bottom of the inlet. The float should be level in either instance.
