    when i bought my new truck avenger, i didnt have my valves adjusted right when i put in the new motor, so i re jetted the front(prinary) of the carb up one size. i didnt touch the secondary. well, now that the valves have been adjusted right, should i re jet it back to the way it was?

    my timing is good, but as ryoken said when he drove her, you can smell some fuel. she doesnt seem to have the power she could have, so i might have the carb professionally tuned.

    thoughts?

    i think ill throw the old jet back in for now and see how she does. could the bigger jet size be giving me the unwanted fuel smell?

    well i put them back to a 68, i was running a #72. i went up 4 when afterwards i read only 2 at a time. feels a bit better performance wise, and my mpg's should incfrease also!

    Yes. And Holley will also tell you to only move 1 jet size at a time. I would do two, but four!? holy crap:blush:
