No, as with most small equipment engines, the culprit is the carburetor. You'll need to soak it in carb cleaner overnight in a sea;ed container and install the rebuilt kit for it.

I assume you refer to a 6500 watt Honda, if it's electric start/and manual(pull cord) First supply a 12 volt battery /if you haven't put fresh gas in it do the best you can to remove all the old gas from the tank and you should find drain screws and small hoses on the lower part of the carburetor. After completing this step add about 1 gallon or so of fresh gas, remove the air filter system from the face of the carburetor ,with a small squirt bottle put a tea spoon or so of gas into the of the carb, close the choke and turn the key, if it fires let it run with the choke closed for only a few seconds then slowly open the choke fully, if the engine stalls close the choke and start the engine again do not leave the choke closed for extended periods as this will cause engine flooding and spark plug failure. Also be sure you have inspected the existing spark plug to be sure it's clean if there is any question about the plug change it.

Make sure that the spark arrester screen on the exhaust isn't plugged with carbon. It takes just thirty seconds to pull it out. If it is clean, then the fuel filters are the next step. Hope that helps. Rod

two things from what I read is the tps sensor and iac valve

stalls can be cause by at least 50reasons (and more for parts bad)
the #1 reason from 1920 to now, never doing tuneups.
ever read the operators guide? on tuneups? by mileage?
bingo

bar none. !
ill list (not a guess) the top three not tune up missed.
1: egr leaks. clean it, but is in the service sched for 50k on most cars made.
2: timing belt slipped.
3: isc sticking ,clean it.

the 50 ways are all under misfire, misfire causes too low RPM at idle
and has 50 failure paths. I can post the link, to the ways.
but will not.

With regrets, I do not have any personal experience with generator troubleshooting. However, I have been informed by some people that have good experience with them that a generator needs to be run for a couple of hours every month to keep the system in proper order. Should a generator sit idle for ten months, the fuel can actually "shellac" inside the carburetor and lines. This will then travel to areas that will gum up - thus the necessity to drain the tank and carburetor completely.
Here is their advice:

Your service person(s) may not be aware of the time the unit sits idle, and if they are aware - then they are not giving you straight facts (in my opinion). I would suggest contacting Honda customer service directly, and explain this situation to them - they will probably be more then happy to have a technician assist you properly. Contact the 'customer relations' number, and they will direct you from there. Here is the link:

I am sorry I couldn't be of more help.

is gas old? is choke on? is fuel turned on?

It may be old fuel and the spark plug is fouled.

Recheck for spark when it stalls. If you have lost spark I would say a heat damaged coil.

You should also drain and inspect the carb bowl. You may have low fuel flow which limits full throttle operation to 30 minutes or less. When it dies you are just refilling the bowl for the next run.

Good luck and be careful!
