I'm using progressive linkage.The secondary carbs don't open until 60% throttle. The secondary carbs have no idle, or power valve circuits, basically dumpers. I run on the primary carb only until I drop the hammer. No problem here. This thing really wakes up. With the .056's, there is an off idle/cruising speed hesitation/surge. No problem with idle, or hard acceleration (opening the secondaries). I've opened the primary jets up to .061, this eliminates the hesitation/surge. It seems to be running "fat" though. Maybe I'll go to .058 and see how it runs there. I thought you may have had some experience with the 2G's. I should have kept the original 2G that was on the motor when I got it. At least I would have a reference point. I just have to play with it a little. I'm happy with the performance overall. Just have to find that "happy medium" between the hesitation concern, and fuel mileage.
Thanks for your input,
Jim Sgrig
