Briggs and Stratton Plastic Pulsa Prime Carburetor (Carb) Rebuild 

This is showing how to remove and rebuild a carburetor on a Briggs and Stratton engine on a lawn mower. This can be applied to any outdoor power equipment powered by a similar engine. This type of carb is found on many different B&S engines from 3 to 5 hp.
The kit is a B&S part # 495770 and comes with the diaphragm, the gasket, filter screen and spring. I bought mine from Lowe's for $4.98 + tax. This is an easy and cheap fix for a engine that is surging.
