    I was nervous buying the used carbs and Its obvious the linkage has been ground out bringing the secondaries in later which may affect the timing of the accelerator pump shot? the shot is done long before they open which in my mind gives it way too much when i'm cruising or part throttle and nothing when I need it when the secondaries are opening and they replaced the secondary metering plates with 12 sizes larger jetting who knows what else they did??? I'm just ready to start fresh. I didn't really have the money either but I'm ready to get this thing done. Me and the kids will eat RAMEN & Mac'N-Cheese for the next month!

    I'm no expert at tuning but I seem to recall that tunnel and cross rams need to be set kinda rich down low so that they don't run way too lean at higher RPMs. Do I have that right fellas? I had some one with way more experience than I set up my cross ram and I seem to recall it being a battle to find that balance.

    I'm no expert, just the driver & check writer, but I know mine is not fat at idle.
    We got mine nice & smooth and can idle under 1000 with zero issues.
    Not bad for a big monster with zero low end, designed to run over 8000.
    There's multiple circuits and multiple air bleeds for a reason.

    Mine fires right up, idles nice, and doesn't die after the burn out even with such a low idle like many do.

    my idle was great my cruise was good and my WOT was good. Issue was 4 big squirters dumping gas and only 4 barrels opening then at the end I have 4 more opening and no squirt. The T-ram actually idled smoother and lower than the single 850

    ok WOT is not quite a strong as the 660's but I think some jet changes will get me there. My oxygen sensor quit some I'm doing it old school for now.
