I just talked to a mechanic who will(I hope) fix my stalling Jeep for good(3 Carters in 3 years). He suggested going with the Weber 32/36. I asked about the legality of putting this on my 90 YJ and said that this year Arizona changed the rules a bit. He explained that the way the Weber was built to run with the K&N air filter, most of the Jeeps he was doing would come in at half their allotted pollutants, better milage and power. This year Arizona says, that the stock air delivery system has to be intacted or it's an automatic failure, regardless of the output.
Weber has an addon to allow the carb to be used with the stock air cleaner assembly. The mech said this reduces the milage and power gains a tad and actually(the Jeeps he's done) increased the output of pollutants.
Leave it to the sometimes stupid government to go this route. I'm thinking about writing my Congressman about this fiasco, especially after the alt fuels mess this state created.
Anyone else in Arizona or other states experience this? He said the Feds pushed this reg on the state or withhold highway funds--blackmail to me, so Arizona might not be the only one that's bass ackwards.
