This is the Briggs flat head engine, if you have good spark, and fuel and engine is craning over and not starting, it is likely that the valves need to be checked for clearance.

Expert:  Curtis B. replied 10 months ago.

The valves have to have clearance, .006 is the correct setting, but as long as there is clearance, it will work. Zero clearance , and you have hard start and poor running, and worse when it warms up.

# ***** and # ***** are the covers that have to be removed to check the valves.
