How to clean and repair a Nikki carburetor on a Briggs and Stratton Intek Engine. Almost all Nikki carburetors are the same on 12 – 20hp single cylinder Intek engines. Not to be confused with The Walbro LMT carburetor also used on Intek engines.
Nikki carburetors are very sensitive to debris and clogged passages, it only takes a little buildup to cause surging. This is how to clean the carburetor to enshure it runs properly, No carburetor cleaner or chemicals required.
I used two pieces of wire for cleaning, one is a piece of bailing wire, the other is a strand from a broken winch cable. You can use a piece from a wire wheel if you don’t have any.
Float Bowl gasket (I call it a base gasket) – B&S # 698781
Float Needle Valve – B&S # 696136
A complete overhaul kit is available, however It costs more and often includes parts that don’t require replacement.
