That's not a Briggs and Stratton engine it is a Chinese GGP engine. There is no diaphragm on it.
There are some problems with this engine.
Check part no. 28 the inlet tube. Make sure it is not cracked.
Do replace the spark plug. No matter how well they spark, under load they can react differently.
Strip the carb and make sure you check that the main jet is not blocked.
Finally check compression.
Check part no. 28 the inlet tube. Make sure it is not cracked.
