    Question Stock carb main jet size

    What comes stock? Of the two carbs I have, the main is miles apart. One runs like dirt, the other better.

    Curious what it should be.

    I ended up replacing a #58 jet with a #69 to richen the mixture slightly. The truck ran much better after that.

    One had a 62 - ran horrible. The other a 70 - runs much better.

    Bring one with you on Sunday. We can compare it with the one or two I have on my bench. Both of those are the same.

    Besides the one in the carb? I will try to remember to bring the small one too.

    The size is miles apart.

    Don't be late. We've got to get to the pumpkin patch tomorrow before I have to leave for yet another freakin' work trip.

    I've driven more than 6400 miles in the past 4 weeks.....
