Quantum engine revs

Hi Mick. Is there a reset with the screws on the Briggs quantum carb? Like the Stihl two strikes wind in all the way then back off 3/4 turn.
Can usually get the engine running sweet at full throttle but when I move the lever to low revs the revs stay the same. Have tried adjusting all three screws. The one just above the bowl with a flat head screw sometimes isn't always there.
Thanks.

Mick

I would just set the lower screw to one and a half to two turns out and adjust it from there.  Sounds more like yours has a air leak, or a linkage issue from your description.

Make sure throttle is closing, and check the intake tub for cracks or holes
