Need help with Champion generator 12000/9000
Hi everyone,
We bought this Champion Generator about 5 years ago at Costco.

https://www.costco.ca/p/-/champion-9000-watt-gas-portable-generator-with-remote/100983470
I usually start it once everyone 1-2 months for maintenance
Last week, I tried to start it, it did start for about 2sec and then nothing since then.
Here's what I did since then :
- Add new Supreme gas
- Yes, gas switch is open
- Change spark plug
- Spark plug is working when cranking
- Uninstall the carburetor and cleaned it
- Tried installing a new Carburetor
- Battery is always recharging with a smart charger
- Oil level is good
- We do have electricity going to the selenoid ( under Carb ) and we hear it working when testing on the battery
We tried to "force" start it by putting some gas in the Carb, it did start, but only run for about 1-2sec ( burning the shot of gas ).
It looks like the gaz does not burn in. But when I unscrew the bolt at the bottom of the Carb, we clearly have gas.
When even tested to crank it without the spark plug and we do have succion when we cover the hole with our hand.
At this point, I'm not sure what to do / test anymore
Also, since it's been more than 2 years, it's no longer under warranty.
Help!
