Hi Jerry, Ive been honest since the beginning, im not a scientist or a professional mechanic. Just your weekend home mechanic that loves classic Chevys'. Nobody had tried this carburetor, so I thought I would check it out and document my experience, like anybody else would do at home. If you get something good out of it, then that's great. Im not recommending anybody buy this carb or not, just an unbiased test from a regular guy.
