I dont think webers are smog legal where smog checks are required. Regardless I basically hated FI for decades, I beginning to see the light now especially at altitudes. The kit on mine used A Chevy 2bbl TB and some basic easy to obtain parts which are easily obtained. Keep in mind your paying the $1200 or whatever they are now for the effort somebody went thru to make the kit. Once you have it all the parts could be bought off Rock auto for probably half the cost to replace the entire setup save the wiring stuff. And yes, the factory carbs on the CJ/YJ were pretty bad.
