Emissions regulations have curbed the use of the L head engine in many places, as it is not as efficient with its exhaust emissions as other types of engines. The compression ratio of any Briggs and Stratton L head engine should be 6:1. The Briggs and Stratton Overhead Valve, or OHV engine, is the replacement for the L head series of engines.
Before deciding on the right oil, it’s essential to consult the manual of the manufacturer or owner’s website for advice. Briggs and Stratton recommend using SAE 30 weight oil for engines with temperatures that exceed 40degF (4degC) as well as SAE 5W-30 synthetic oils for those temperatures lower than 40degF (4degC).

If the 625E is 190cc yet only produces the same torque, then it shows the advantage of the 625EX engine with the same power from 150cc. I would expect fuel consumption would be better with the 150cc engine. The easy-start with self-prime on the EX is fantastic. . 312 143 365 50 337 244 217 224 161
