I agree.. Fuel or ignition.

Here's what I'm running:

 

Idle: 60f8

Main: 145

Corrector: 160

Pump jet: 45

E-Tube: F2

 

For whatever its worth... Dave at Rebello told me to use for my New 3.0L being shipped to me:

 

Choke     38mm

Main Jet  165

Idle Jet    60F9

Air Corrector 200

 

I would assume for a 3.1L your settings shouldnt be far off...

Are you running 40s or 45s?

(I ought to have the O2 sensor welded in this weekend, hopefully....)

Definetly sounds like somethings going on like a miss or something. You need to install an o2 sensor to eliminate fuel issue. Could be running lean at top end. I'm probably running running your numbers with my L24.

 

 

After tuning the Webers and getting an O2 sensor installed everything is getting better. I've found a or the main problem with the power output. My high tension wire was not seated in the distributor. Sometime in the past I pushed it down and shoved the metal connector into the boot. The ignition system was having to make a jump of nearly an inch. Installed a new wire and the car really came alive. Regarding the AFR, been running a bit rich. I've got some new E-Tubes and idle jets. Installing them this weekend. My weber updates are in the "lives for triples" thread.
