You can adjust your VW carburetor by using the adjustment screws. There is an adjustment screw to adjust the flow of fuel. There is an adjustment screw to adjust the flow of air.

First, you will want to be sure that it isn't flooding. Be sure that the automatic choke is working properly. Set the timing to factory specifications. Then you can only adjust the idle fuel air mixture. If it continues to run rich then the carburetor is most likely the fault.

It would be a very complex process...as the car has fuel injection and no carburetor My 380 SEL does have a carb, I just replaced it. Does anyone else have a suggestion, short of taking it to a dealer or mechanic?

If it has a carburetor, then there should be a screw somewhere on the carburetor. If it's fuel injected, then I don't think you can adjust the idle without hacking into the computer.

Adjust the carburetor although being that old the carburetor may be in need of a rebuild with a rebuild kit. Rebuild kits come with directions.

To adjust the carburetor on a Yamaha badger is really simple. There will be two screws one is a slotted head and the other is a four way. To adjust the carburetor you have to turn the screws clockwise until the engine idles fast.

The 1989 Chevy Caprice 305 V8 does not have a carburetor. It is equipped with Throttle Body Fuel Injection which may look like a carburetor but is not.

I'm no mechanic, but from what I have read, the later model engines have hydraulic lash adjusters that can be tested and replaced(Haynes manual).

My kodiak 400 2003 idles well but when you throttle away it chugs like its no getting any fuel does any one have any clues

Lawnmower engines are reliable devices, and should not require any adjustment. The main thing that should be adjusted or replaced is the throttle cable length and position, and the governor springs.
