I have a model 190432-2535 briggs and stratton 8 hp engine and I need help with resetting all three carb screws. Any ideas what they should be?

Screw all the way in and turn back out 1 1/2 turns to try and start with. Some of the older carbs are bad about "wearing" in the shaft holes through the body of the carb and will never run correctly. And if they do, it usually doesn't last very long.

That's only part of the procedure.

Do it to both mixture screws.

Once it "runs":

1. Go to "fast" idle and adjust the larger screw for a smooth idle.
2. Then go to a low idle speed and adjust the smaller screw for a smooth idle."

You can reverse the order.

How do I adjust the screw on the bottom of the bowl?
