In this pictuer you will see where the orifice is that I drilled out to 0.040.
If you wanted you can buy a set of carburetor jet cleaning files and make the orifice really small but larger than factory.
Buy doing this and/or changing ratios of mix you can customize the device.
It also looks as though you could do some modifications make the orifice really big and come back with a needle valve to make adjustments.
