AFR meter tuning help

[soopertruper]

I finally took my truck out today for a good long ride, about 50 miles with my new afr meter. At a cruise(2500-3000 rpms), the meter reads between 10.0 and 11.0. way to rich. What am I looking to change? Acceleration is also a little bit rich, but I know I can play with the pump cams, but everything else is pretty well dialed in. Thanks, Damon

Damon, is that a Holley? If so, what model? And does it have external air bleeds? I'd start with the primary jets. That'd have the most affect on cruising. The 2500 - 3000 RPM is at 60 MPH or so?

.......... What's your vacuum when cruising at 60? You'd want to make sure the power circuit (power valve on a Holley) isn't pulling in when cruising.

.......... The cams, etc. for the accel. pump has little to do with A/F ratio.

Oh yeah, sorry its a holley street avenger 670. I haven't checked my vacuum yet, just sat down to start reading my holley book. tomorrow is another day! 2500-3000 rpm's is a highway speed probably 55-65? speedo doesn't work at the moment.

Scotty, you headin down to e-town anytime soon?

No, no Englishtown anytime in the very near future. Been too damned busy. I need to do a few things to the truck, I'm thinking mid-July I'll be out of the hole. Mid July, Ya know, when it's hot as hell. http://www.s10v8.com/images/smilies/icon_mad.gif

Yeah, I'll be lucky to be able to get down there by mid to late july if at all. 4th year with the truck and still haven't managed to get there once. I swear this is gonna be the year!!!
