hey all, i'm heading out to the dragstrip today to give my new zex setup a try. i have been doing some reading of some older threads and i gathered that retarding the timing may not be necessary until you are going with larger shots. i'm running a dry system that currently has the 55hp jet installed. zex says no timing adjustments are required. if i opt to put in the 75hp jet, zex recommends 4degrees retard. per an old thread in '02, they say timing "should" be fine at stock ... but i am only running 91 octane here in california.
fwiw, i do have the colder ngk's gapped at .035".
input?
