Well I futzed with it this weekend & got it to idle better. I tried throttle plates with an 1/8" hole, played with boosters, power valve block, air bleeds, float level & some other stuff. It now idles on the mixture screws w/adjustment, nothing coming out of the boosters. I can idle it down, some, without it dying. It's a lot snappier. But I am back with the 1/4" hole throttle plates. Just gotta get it back on the track & see what I've done to WOT jetting & if that 5800 thing is the springs or carb. Thanks for the input. Appreciate it.
