    1988 V135 Reeves timing method vs the Merc book?

    you can set either one first at crankin'... first or second.. max should never change after ya "loc" down tha jam nut... tha only things that can change tha max would be a module that hooks up on a switch box.. ie: idle stab or limiter.. (or another electrical part involved with ign) both of...

    1988 V135 Reeves timing method vs the Merc book?

    first i'll agree its not IDLE timing.. at least in any nomenclature.. its something that has worked its way into tha description because of tha results of changin' PRI pick up timing.. tha throttle linkage is what determines when tha butterflies move.. tha timing moves tha instant you move tha...

    there is no confusion at all... they all are set in tha same way, jus different numbers.......... idle/pri has nothing ta do with changing max on tha V6 merc........... there are all kinds of tricks ta do with timing and linkage adjustments.. if ya not completely up on what works and what...

    1988 V135 Reeves timing method vs the Merc book?

    gotta beg ta differ.............. pri. and idle are same thing on these things.................. pri determines idle rpm and speed.. nothing else determines that'' (except idle air jetting).. guess thats why some folkjs (myself included) refer it ta "idle timing"... most say 0 ta 9 ATDC.. some...

    you seem ta be one of tha lucky ones with tha temp gauge reading!.. 150 is 'bout normal.. those type gauges can be all over tha place as for "position" of tha needle.. tha only way ta be sure of temp is with a gauge/water temp sensor.. trust tha warning buzzer more than tha gauge...
