B&S 18 HP valve Adjustment
Hello; I decided to adjust the valves on a B&S 18 HP twin today by following the instructions from another post. The engine is MODEL 422707; TYPE 1522 01; CODE 9308185A. I could not see a rocker arm cover after removing the shielding, so I stopped and put everything back. I could see a finned cylinder head in which the spark plug is located. I suspect this engine does not have adjustable valves such as those described in Vanguard/ non Vanguard valve adjustment post.
