My honda gx160 generator keeps cutting out after 2 mins

Hi pulsing is usually a sign of insufficient water flow to the unit.
always get the largest water hose you can for the feed and check to see if your water system can keep up (if it is a three gallons per min machine grab a bucket and make sure you are getting at least 3 gallons per min before you plug the machine in.
The number one culprit for bad flow is the ez hoses or retractable hoses.

There are a few things i can think of that would cause that problem. #1 clean out the carb, some times when an engine sits for a little while the gas will gum up in the carb. #2 check the tuning on the carb, It is possible that the idle screw needs a bit of adjustment. #3 The gas could have gone bad. Again if it sits for a while and the gas cap doesn't seal properly your gas will go bad in a hurry.
Hope this helps.

check EGR

I suggest that the rings are now soft or broken and not sealing or the valves are stuck open unless it is a 2 stroke. Gen sets have a low oil cut out switch that stops the motor immediately there is insufficient oil in the sump. I wonder why it allowed you to run the engine for 10 minutes as it will not even allow you to start with no oil.

Linda, Sounds as though the engine is starving for fuel.

Hi, check the oil level. If low the oil guardian is cutting the spark. Regards Phil.

Is the ignition switch turned to "ON" . Is it full of oil?

Do you maybe have regular gas in it? Both Canadian and US regular gas now have ethanol in them and if the generator has sat for 2 weeks or longer then the gas is bad.Remove the gas tank and look inside. You will probably see an off-color blob floating around in the bottom. That is our wonderful environment friendly ethanol doing what it does best. Drain the tank and refill with premium. Restart the engine and do what you need to keep it running for about 5 minutes. If it has the plunger primer for cold start, use it every time the engine starts to die, 2-3 pumps each time. If not dribble a little gas into the breather to keep it going. After about 5 minutes it should start running on it's own. If not you will likely have to remove the carb and get the rubber seals replaced. Ethanol and rubber don't mix well.

After this keep premium gas in all your small engines. It doesn't separate. If you want to keep using regular gas then there are additives in the after market that will help keep it from separating. Hope this helps.

check the oil level and top it up its most liky low and low oil shutdown is kicking in

if it still wont run try checking main jet , then try cleaning out carb and replacing plug

then check for tight in / ex valve s

cheers

You probably need a new coil, if it is a 2 stroke then it will almost certainly be the coil. The defect is very typical and recognizable.
