You may not need them, check and see first, might just be filthy, or need the flaot needle/carb gasket set? But what the hell, for a measly $8 plus shipping you can get them from Partsnmore, think I just got a set for $51 with stock jets, and you can get new jets from Tommy at Lowriders by summers for $10 a set plus shipping, $5? priority....
