Re: Need help tuning a carb
The air/fuel mix screw is the one closest to the engine going in at a steeper angle than the rest. I generally turn it slowly inward until I hear a noticeable change in engine sound (keep it running at about 1/2 throttle), then count the turns outward until I hear another noticeable change in sound. Then I turn it back in half of those turns and "meet it in the middle."
I gave up adjusting carburetors to spec a long time ago and this provides great results each time I do it.
