12.5HP 1993 286707

Hi, I’m wondering how\where to set the valve clearance on this engine. There doesn’t seem to be a valve cover where it’s easy to get to them.

Anyone have a manual please?

Thanks
Justin

It's not an over valve engine...
 
Part #1330 is the manual:
https://jackssmallengines.com/jacks-parts-lookup/manufacturer/briggs-stratton/briggs-stratton-engine/200000-399999-series/286700-to-286799/286707-0441-01/crankcase-cover-sump-engine-gasket-set-cylinder-oil-valve-gasket-set-crankshaft-piston-rings-connecting-rod
 
 
To access the area to adjust, the carb and intake manifold need to be removed.  
There's a crankcase breather (part #10) that has to be accessed to get to the valve adjustment.
 
If a larger gap is needed, the valve has to be removed and SLIGHTLY GROUND DOWN on the tip (we're talking potentially .001" and up):
