Re: CHAMPION 4000 W Gen-Set
I guess it is a tinkering project for you but it pains me to see the of all the work done.
I would have blown out the end cover with air hose and never taken the cap off.
It is a typical chinese engine with Huayi carb. MAny honda parts fit but yo sholdn't need any. I would have cleaned out carb well and fired it up and see if it produces power. If not you excite the field with a electric drill. Most gensets are fine. They just have a clogged up carb.
Note on these carburetors: Anytime one will start and run but surges, it is the "idle circuit" or what it left of it.
The roundish push in plastic plug under the min speed stop screw (also plastic) has a tiny jet in the end of it that must be clear to run perfectly.
I always just clean the main jet up in the aluminum tube of body or carb in the bowl first but if it surges after that, then the other one is plugged.
Don't buy any parts from Champion (if you can).
Get the number and get anything on ebay.
These complete carbs are under 17.00 shipped to your door but the manufacturer of the generator will charge you 65-85 plus shipping.
The other problem with these is the voltage regulator goes out. Also available for a fair price on ebay.
Never put any fuel in the tank that is not fresh (same day bought) stabilized fuel.
1 oz of StaBil for each gallon on fuel.
StaBil into empty gas can, add fuel. Go home and fill up item
Store it full to prevent tank rust on steel tanks.
They were using plastic for a number of years but there was a recall due to leaks at cracks and the all went back to steel.
Start and run once a year or so for 20-30 mins and check ac output. Continue to top off with fresh stabilized fuel or eventually even stabilized fuel will go bad and gum up.
