I recently went to NAPA to get a rebuilt carb (Rochester 2G for the 225 V-6). After hours of messing with it I finally took it to the mechanic, who told me it was a bad carb (bad accelerator pump). NAPA replaced it with another rebuild, same story. Spent hours messing with it, thought I must be an idiot (which may or may not be true), took it to mechanic, he said it was another bad carb. In addition to the price of the carb, I've now spent about $200 at the mechanic only to find out that the NAPA carbs are crap. Should I keep trying until I get a good one from NAPA, or is there an upgrade carb (ie. Holley) that can be easily adapted to the 225? Thanks.
