Hi my name is ***** ***** welcome to just answer. , yes that is high , 120 to 140 is is well over the 90 psi needed but 180 is really high, is it not running ? , what is the model number ?
Customer: replied 2 years ago.
RY28140.. cleaned the carb but still the same... Starts after flooding the carb but then stops

Ok , have you checked the filter in the gas tank to make sure the gas flow isn't restricted ??
Customer: replied 2 years ago.
checking now.. Actually, now the engine keeps running (improvement after cleaning the carb) as long as I press the throttle... When I let go, it shuts off and won't restart unless I press the fuel bulb once or twice.

filter is clean

Is it still pulling gas when it dies ?
Customer: replied 2 years ago.
yeah.. It only dies if I let go of the throttle

It's the carburetor it won't hold a idle , it one of the air fuel mixture passage ways are blocked or if it has high and low needle set screws if they are turned in to tightly it can damage them
