it idles pretty fast and takes a long time to settle down into a nice purrrr... fast idle is not enough to move the truck, but its idling so fast that it sounds like its missing.. like instead of the bwahhhhh it goes weeee de de de de weee.... iv tried messing with the low speed settings by richening it up and leaning it out, but it doesnt want too idle right??? I havent sealed my engine yet, think it may have an airleak? and should i use some of that sensor safe stuff for automobiles to seal up my engine?

Thanks,
Anthony

What happens when you close more the slide(airgap) by unscrewing the air-screw?

LSN to rich, Lean it out, check your air filter. Mine did the same thing, changed air filter and leaned the LSN, everything is OK after that

try closing more the idle-needle, if the idle drops all the time it then could be you are just too rich.

If you still cannot manage to find the right tune, then I suggest to have your LHS or Dealer to take a look at this.

AWSOME!!! I had my idle set too high.... I guess I was expecting it too idle a little longer. Right now the bottom end is nice and powerfull, but doesnt idle but for maby 3-5 seconds (telling just by sound, I never actually let it die),but then again these engines werent built too idle. Im so happy =)

mine will idle a whole tank.. read that thread.. it can be done.. but ya got to learn how to tune before you can acheive that situation.. something you need to be very carefull with on this all is if the LSN is too rich, you over compensate by leaning the HSN to get the LSN right and the HSN right you will see it will idle forever with little issue.. its just learning how to tune which i hate to say, with a rb can be a tad tricky, but once learned can be used on any engine

Think a little hotter plug will help it too? Im running the #6 right now, so if lower is hotter (am i right?) should I pick up some 5s or 4s?
