Oil Vapors From Carburetor

I have a 2017 Ariens deluxe 24 snow blower with a Briggs and Stratton 15C134-3023-F8 that is labeled 1150 below the fuel tank. 

The symptom I have is the carburetor is expelling oil vapor droplets. I saw some youtube videos to look at the rocker arms to see if the exhaust rocker is moving the same amount as the intake rocker arm due to a worn cam lobe. When I removed the rocker arm cover the valve cap for the exhaust rocker arm fell out, which is supposed to be just below the rocker arm. I am presuming that valve lash is incorrect.

I have an older edition of the "briggs and stratton single cylinder OHV repair manual part number 276781" that was printed April 2002. Does anyone have a newer copy of the manual?

I need the specs for valve lash and torque values for the rocker stud and lock nut securing the rocker arm.

I have found most any owners manual and many repair manuals by google search. It seems if the cap came off the cam lobe may indeed be worn. I would simply set the lash the same as the intake and check the valve lift on both intake and exhaust. That may tell you all you need to know.

Hello Obie, Thank you for the leads. Briggs and stratton's website only offers owner's manual and parts diagrams. Jack's small engines website offers the book I needed.

Hi Michael, Lash: Most Briggs and Stratton engines: Intake .004 and exhaust .005. This engine should have a nut with a Torx screw in the middle to lock the nut. Check setting after Torx screw is tightened. If cap came off it is definitely a lash issue. Make sure the push rod has not bent slightly. Parts are available on the ereplacementparts​.​com site usually. The rocker cover can…

Hello Glenn, Thank you for the helpful tips. The oil vapor amount coming out of the carburetor is a lot like steam from a kettle and dripping out of the plastic covers making me think there was some kind of leak. I will check to see if the there is a breather other than the rubber hose elbow exiting the side of the valve cover. From videos from a knowledgeable person called Taryl fixes all who…

Hi Michael, I am familiar with Taryl Fixes All on You Tube, he acts and dresses like a nut, but he knows his stuff. (It's an attention getting step). The rubber hose going to the intake comes from the breather on the side of the crankcase. They used to be bolted to the side of the block, but the designs have changed over the years. B&S shifted to overseas production years ago and their QC…

I adjusted the intake and exhaust valves lash to 0.004 and now the engine seems to run well again. Thank you to everyone for the help.
