I have the same problem and I am going home to fix it this afternoon. The intake valve is not sitting perfectly tight against valve seat (block opening). It is slightly open when the plug fires it will create a small back fire through the carburetor I can only guess that the engine will run rough sorta when this happen. it is getting a little explosion in the cylinder, enough to stroke the piston, but will let some of the explosion be through the carburetor Take the head off and clean the area where the valve stem sits against the head. once clean, apply some toothpaste in this seat area and put the valve stem back in place and rotate back and forth to "polish" this seat area. do this for about 30 seconds. clean off the toothpaste and reinstall valve, spring, keeper, and head. make sure head bolts are tight. p.s. make sure that the valve is fully seated when the spring and keeper are installed, to make sure the valve is closed tightly to prevent any explosion bypass. God bless.
There is no aftermarket for this carburetor kit at this time. It is only available from Briggs & Stratton.

A Briggs and Stratton L head twin engine wills pit gas out of the carburetor and flood out when starting if the diaphragm has been damaged. This will cause excessive fuel to enter the carburetor.
Clean out the carburetor with gas, the reason it wont keep running is its not getting enough gas through the carburetor.

Is the rumor true? Is Briggs Stratton going out of Business?? We were told not to by lawn mowers with the Briggs stratton motors.
No, never oil the carburetor linkage. Clean the linkage throughly with carburetor cleaner. If you oil the linkage it will become clogged with dust which the oil will attract.
