Spark arrestors are often required in State parks etc and areas of high fire risks. They are designed to prevent hot glowing carbon from the exhaust blowing out and starting a fire. Not sure really why they are opional as I doubt they cost much?

The flickering is caused by fluctuating frequency due to engine speed, thes egenerators really are not recommened for powering home systems. It shows up in flourescents when the freq dips around 57HZ and 63HZ

Under load? or idle?Check oil level pressure switch and level

Check that you have power on the generator side of the circuit breaker, check each leg to neutral and you shoudl see 120V approx. If you still only see it on one side you have a bad stator. if you see it on both legs measure across them L1 L2 and you should have 240V, then check again on the receptacle side of the breaker, if you don't have it you need a new breaker

It depends on the environment, hot dusty, or normal.Generally first time at 50 hours then 150, or once a year whichever comes first.

The fuel mixture is way too lean, or a burnt valve. Check the spark plug color it should be bisuit brown, if it is grey then suspect the above.

I would recommend you take it to someone who can diagnose it for you. it could be, but it could also be many factors. It maybe worth a $50 diag fee. Causes can be too numerous to post

To flash a generator, I assume it has set for a long long time, or else it isn't needed unless you installed a new non magnetized rotor. To do it, disconnect the wires note their position and polarity that conenct to the brushes. Connect a battery with an in line fuse momentaraily for about 2-3 seconds (make sure the polarity is correct IE B+ on the right ring) This will build a correct polarized field for the rotor that will build when induced in the stator

Check the capacitor first, then ohm the windings out, do you get any voltage?

check the oil level cut out on the engine is all plugged in

bad fuel? or varnished inside of carburetor needs to be removed all ports and jets thoroughly cleaned out should solve your problem

Replace the sockets they have most likely gone bad, I have found this on a lot of generators I've worked on.

It has to be either a fuel or ignition problem. Have you checked the spark? Was it stored with gas in it?

Engine speed is low, does your meter read frequency? Set for 60 Hz @ speed. I doubt there is a voltage regulator adjustment. This may help If you need further help, I’m available over the phone at https://www.6ya.com/expert/craig_3fa289bf857b1a3c

first check n c do u have any fire at d plug then if so check carb maybe its clog need to be torn down
