stay on the AVS & work with the float arm till you get it level/correct setting & then see how it performs. All OE AVS's are lean from the discombobulated gov't emission regs of the time & can benefit from converting to the eddy performer 2 step rods/short pri jets in one of their strip kits that is close to but slightly richer on the rods/jets than what is in the AVS now or swap AVS stuff if you have extras. If you ever get to Lincoln I would love to take a look at it. EDIT what Sniper said just bend the "connector tang" in the middle till the float is level (I'm assuming "level" is the float setting). Dont put any pressure on the needle/seat in this process. let the float rest lightly on it after each adjustment till you get it where you want it.
