Someone gave me a predator clone of a gx390 or 420.  It needed some general tlc and new gas tank but it's running well now and driving a 7500 gen head for me. After thoroughly cleaning the gooked up carburetor it's running very rich. I can't find a mixture adust anywhere.  Am I just missing it? Do I have to change the jet?  Anyone have a clue on that?  Thanks

If it is like the Honda carb it will have a removable emulsion tube above the jet. Remove it and make sure the tiny air bleed holes are clear.

Thanks.  That sounds like the culprit.  This carb was full of goop. I probably didn't get those holes clean.

The Gov. took those screws away from us...

  That ain't all they took from us!

Well now we know where they got the screws to put to us.
Old LT40HD, old log truck, old MM forklift, and several huskies.
